The correct option is (c) 2 and 3 only.
Explanation
Vitamin C, chemically known as ascorbic acid, is a water-soluble vitamin that plays a critical role in the synthesis of collagen, absorption of iron, and maintenance of the immune system. Unlike fat-soluble vitamins, it is not stored in the body in significant amounts and requires regular dietary intake.
Statement 1 is Incorrect: Vitamin C is primarily found in fresh fruits and vegetables, particularly citrus fruits (oranges, lemons), amla (Indian gooseberry), guavas, tomatoes, and green leafy vegetables. Dry fruits and nuts are generally poor sources of Vitamin C; they are typically rich in healthy fats, proteins, and other micronutrients such as Vitamin E and B-complex vitamins.
Statement 2 is Correct: Vitamin C is a potent antioxidant that strengthens the body’s immune defense mechanism. It supports the function of various white blood cells, thereby helping the body fight against infections and diseases.
Statement 3 is Correct: Vitamin C is chemically unstable and is considered one of the most heat-labile vitamins. It is easily destroyed by heat during cooking, as well as by exposure to light and air. Prolonged cooking or washing cut vegetables can lead to a significant loss of this vitamin.
Key Takeaway: Vitamin C (Ascorbic acid) is a heat-sensitive, water-soluble vitamin essential for immunity and collagen synthesis, found abundantly in citrus fruits and vegetables rather than dry fruits or nuts.
