The correct answer is Ethanol + Methanol​.

• Ethanol + Methanol​ is denatured alcohol.
• Denatured alcohol is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption.
• The term denatured alcohol refers to alcohol products adulterated with toxic and/or bad tasting additives (e.g., methanol, benzene, pyridine, castor oil, gasoline, isopropyl alcohol, and acetone), making it unsuitable for human consumption.
• The most common additive used is methanol (5–10%), giving rise to the term methylated spirits. Denatured alcohol is used as a lower-cost solvent or fuel for home-scale or industrial use.

Key Points

• Denatured alcohol is ethanol or grain alcohol that contains additional chemicals called denaturants that make it unfit for human consumption.
• Denatured alcohol is fine for some types of lab work and as an ingredient in certain products, but it's not safe to drink.
• Ethanol is an organic chemical compound. It is simple alcohol with the chemical formula C₂H₆O.
• Its formula can be also written as CH₃−CH₂−OH or C₂H₅OH and is often abbreviated as EtOH.

Additional Information

• Alcohol (ethanol or ethyl alcohol) is the ingredient found in beer, wine, and spirits that causes drunkenness.
• Alcohol is formed when yeast ferments (breaks down without oxygen) the sugars in different food. 

The correct answer is 4°C.

• Freezing of Water:
  • As water freezes, cold water (or ice formed) comes on the surface and warm water goes down.
  • Since the freezing temperature of the water is 0ºC or 273 K.
  • So water at the bottom should be at a higher temperature.
  • Water density at 4ºC is more than the density of water at 0ºC, hence the correct option is 4ºC.

​Key Points

• Reason of low temperature at bottom of the top layer:
  • This is due to the process of convection.
  • When the temperature of the water at the top layer reaches the freezing point, it is converted to ice.
  • But ice is lighter than water, so it will not sink to the bottom.
  • So there will be ice on the top surface and water would remain at the bottom of the lake.

  • Malware is any software intentionally designed to cause damage to a computer, server, client, or computer network.
  • A range of antivirus software, firewalls and other strategies are used to protect against the introduction of malware.

Key Points

• Operating system
  • An operating system is a large and complex system.
  • OS system components include:
    • File,
    • Process,
    • Memory,
    • I/O device management.

 Additional Information

• The process management component
  • The process management component is a procedure for managing the many processes that are running simultaneously on the operating system.
  • Every software application program has one or more processes when they are running.
  • For example, when we use a browser like Google Chrome, there is a process running for that browser program.
  • All these processes managed by process management. 
  • The process management uses memory allocated to them and shutting them down when needed.
• File management
  • File management in an operating system includes file creation and deletion.
  • Manipulating files and directories.
• Memory management
  • ​An Operating System performs the functions for Memory Management such as:
    • It helps to keep track of primary memory.
    • Determine what parts of it are in use by whom, what part is not in use.
• I/O device management
  • ​An Operating System performs the functions for I/O device management such as:
    • It offers buffer caching system
    • It provides general device driver code
    • It provides drivers for particular hardware devices.
