Which vitamin is destroyed by heat?

Correct option is C

Ans. (c) Vitamin C
Sol. Vitamin C (Ascorbic Acid) is highly heat-sensitive and gets easily destroyed by cooking, boiling, and prolonged exposure to heat. It is a water-soluble vitamin essential for immune function, collagen synthesis, and antioxidant activity.
Explanation of each option:
· (a) Vitamin A – Fat-soluble and relatively heat-stable but can degrade at very high temperatures.
· (b) Vitamin E – Fat-soluble and heat-resistant, though it may degrade slightly under extreme heat.
· (c) Vitamin C – Correct answer. It is highly heat-sensitive, making it prone to destruction during cooking.
· (d) Vitamin K – Fat-soluble and heat-stable; not easily destroyed by heat.
