Correct Option
Pair 1: Vitamin C deficiency causes Scurvy, a disease characterized by symptoms such as bleeding gums, joint pain, and poor wound healing. This pair is correctly matched.
Pair 2: Vitamin D deficiency leads to Rickets in children, a condition involving the softening and weakening of bones due to impaired mineralization. This pair is correctly matched.
Pair 3: Night blindness is a condition primarily caused by a deficiency of Vitamin A, not Vitamin E. Vitamin E deficiency is typically associated with neurological problems, muscle weakness, and hemolytic anemia. Therefore, this pair is incorrectly matched.
Based on the analysis, only pairs 1 and 2 are correctly matched.
Incorrect Options
Option (b) is incorrect because pair 3 is mismatched; night blindness is a symptom of Vitamin A deficiency, not Vitamin E deficiency.
Option (c) is incorrect as pair 3 is not correctly matched.
Option (d) is incorrect because pairs 1 and 2 are correctly matched, making option (a) the correct choice.
