The correct answer is option 3. A-III, B-II, C-IV, D-I.
Let us go into detail about the associations between each vitamin and their related disorders:
A. Ascorbic Acid (Vitamin C):
Disorder: Bleeding of Gums (III)
Explanation: A deficiency of vitamin C leads to a condition known as scurvy. One of the symptoms of scurvy is bleeding gums, which can progress to more severe oral and systemic issues. Ascorbic acid is crucial for the synthesis of collagen, a protein that provides strength to connective tissues, including those in the gums.
B. Vitamin D:
Disorder: Osteomalacia (II)
Explanation: Vitamin D plays a vital role in the regulation of calcium and phosphorus absorption in the intestines and their utilization in bone mineralization. Deficiency of vitamin D can lead to softening of the bones, a condition known as osteomalacia in adults and rickets in children.
C. Riboflavin (Vitamin \(B_2\)):
Disorder: Cheilosis (IV)
Explanation: Riboflavin is essential for various metabolic processes, including the metabolism of fats, drugs, and steroids. Deficiency of riboflavin can lead to cheilosis, which is characterized by inflammation and cracking of the lips, especially at the corners of the mouth.
D. Vitamin A:
Disorder: Xerophthalmia (I)
Explanation: Vitamin A is crucial for maintaining the health of the eyes, and its deficiency can lead to a condition called xerophthalmia. Xerophthalmia is characterized by dryness, night blindness, and, if left untreated, can lead to irreversible blindness.
So, the correct match is 3. A-III, B-II, C-IV, D-I |
