Hence, ‘37’ is the answer.

The correct answer is Vitamin C.

Important Points

• Scurvy is a nutritional disorder of humankind.
  • Scurvy is caused by the deficiency of Vitamin C
  • Ascorbic acid is the chemical name of vitamin C.
  • Vitamin C is the first artificially synthesized vitamin.
  • Vitamin C is essential for the healing of wounds, repair, and maintenance of cartilage, bone, and teeth.
  • Vitamin C deteriorated through cooking and canning of food.

Additional Information 

• Xerophthalmia and night blindness are the deficiency diseases of Vitamin A.
• Rickets is the deficiency diseases of Vitamin D.
• Hemorrhage is the deficiency diseases of Vitamin K.

The correct answer is Rajasthan.

Key Points

• 'Ghaggar and Banas' are rivers that feed the state of Rajasthan.
• The Ghaggar is an intermittent river in India, flowing during the monsoon rains.
  • It originates in the village of Dagshai in the Shivalik Hills of Himachal Pradesh at an elevation of 1,927 meters (6,322 ft) above mean sea level and flows through Punjab and Haryana states into Rajasthan.
  • The main tributaries of the Ghaggar are the Kaushalya river, Markanda, Sarsuti, Tangri and Chautang.
• Banas River :
  • The Banas is a river that lies entirely within the state of Rajasthan in western India.
  • It is a tributary of the Chambal River, itself a tributary of the Yamuna, which in turn merges into the Ganga.
  • It flows northeast through the Mewar region of Rajasthan, then across Hadavati before meeting the Chambal near the village of Rameshwar in Sawai Madhopur District.

The correct answer is Butane.

Key Points 

• Liquefied Petroleum Gas (LPG) is a blend of light hydrocarbon compounds.
  • It mainly consists of butane or propane or a mixture of both.
  • At room temperature, both gases are colourless and odourless.
  • It is a mixture of 48% propane, 50% butane, and 2% pentane.

Additional Information

• Water Gas:
  • Water-gas is a mixture of CO and H₂.
  • However, by-products such as char, tar, soot, ash, and condensates are also produced. 
• Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.
• Compressed natural gas is a fuel that can be used in place of petrol (gasoline), diesel fuel, and liquefied petroleum gas (LPG).
  • CNG combustion produces fewer undesirable gases than the aforementioned fuels.
  • In comparison to other fuels, natural gas poses less of a threat in the event of a spill, because it is lighter than air and disperses quickly when released.
