In this question shows that in option 1, 2 and 4 we add three in first letter we get second letter but in option 3 we add 1 in the first letter we get second letter. 

A - D : Difference of two letter

S - V : Difference of two letter

G - H : No letter in between

L - O : Difference of two letter

G-H is different from others.

Hence, option 3 is the correct answer. 

A storage unit is used to store information and instructions when they are not being used in memory.

Three kinds of storage devices are a flash drive, hard disks, and CD - ROM drives.

Data access time is the time taken by a computer, or a data storage device or medium, to respond to a user's request for data.

Typical access times for a CD-ROM drive, 200 milliseconds; hard drive, 15 milliseconds; Random Access Memory (RAM), 70 nanoseconds.

There is a trade-off among the three key characteristics of memory: namely, capacity, access time, and cost. A variety of technologies are used to implement memory systems, and across this spectrum of technologies, the following relationships hold:

• Faster access time, greater cost per bit
• Greater capacity, smaller cost per bit
• Greater capacity, slower access time

The Correct Answer is Cytokinin.

Key Points

• Cytokinins are a class of plant growth substances (phytohormones) that promote cell division or cytokinesis in plant roots and shoots.
• There are two types of Cytokinins: Adenine-type Cytokinins represented by Zeatin, Kinetin and 6-Benzylaminopurine and Phenylurea-type Cytokinins like Diphenylurea and Thidiazuron (TDZ).

Key Points 

• Auxins are a class of plant hormones with some morphogen-like characteristics. Auxins play a cardinal role in the coordination of many growths and behavioural processes in plant life cycles and are essential for plant body development.
• Abscisic acid is a plant hormone. ABA functions in many plant developmental processes, including seed and bud dormancy, the control of organ size and stomatal closure.
• Gibberellins are plant hormones that regulate various developmental processes, including stem elongation, dormancy, germination, flowering, flower development and leaf and fruit senescence.

The correct answer is Plaster of Paris.

Key Points

• Plaster of Paris is the generic name of calcium sulphate hemihydrate-CaSO₄. 1/2H₂O.
  • Plaster of Paris is manufactured by heating gypsum at 423K or 150^o C/300^o F.
  • On heating gypsum at 423 K, it loses water molecules and becomes calcium sulfate hemihydrate. This product is known as the plaster of Paris.

Important Points

• Application of Plaster of Paris-
  • It is used as a building material as a protective coating on walls and ceilings.
  • It is used as a moulding and vesting agent for decorative elements.
  • It is also used for aesthetic touch to the construction elements.
  • It is also field as plaster in orthopedics and as a filling material by dentists, etc.

Additional Information

• Baking soda is also known as sodium bicarbonate or bicarbonate of soda.
• Vinegar is also known as acetic acid. It typically contains 5–8% acetic acid by volume.
• Washing soda is a chemical compound with the formula Na₂CO₃, also known as sodium carbonate.
