Consider the following pairs : Vitamin - Deficiency disease 1. Vitamin C - Scurvy 2. Vitamin D - Rickets 3. Vitamin E - Night blindness Which of the pairs given above is/are correctly matched?

1. Pair 1 is correctly matched. Deficiency of Vitamin C (Ascorbic acid) leads to Scurvy, characterized by symptoms like bleeding gums, weakness, and skin problems. 2. Pair 2 is correctly matched. Deficiency of Vitamin D impairs calcium absorption, leading to bone softening diseases. In children, this is known as Rickets, and in adults, it is called Osteomalacia. 3. Pair 3 is incorrectly matched. Night blindness (Nyctalopia) is primarily caused by a deficiency of Vitamin A. Deficiency of Vitamin E (Tocopherol) is relatively rare but can lead to neurological problems and anemia. Therefore, only pairs 1 and 2 are correctly matched.
