• A. Beriberi
• B. Scurvy
• C. Rickets
• D. Blindness

Hint:

Vitamin deficiency diseases to remember:
Vitamin A → Night blindness
Vitamin B1 → Beriberi
Vitamin C → Scurvy
Vitamin D → Rickets (children) / Osteomalacia (adults)

Answer 1

The Correct Option is C

Step 1: Understanding Vitamin D and its functions.
Vitamin D is a fat-soluble vitamin that plays a crucial role in calcium and phosphorus absorption in the body. It is essential for:
Maintaining normal blood levels of calcium and phosphorus
Promoting bone mineralization and growth
Supporting immune function
Step 2: Sources of Vitamin D.
Vitamin D can be obtained from:
Sunlight exposure (UV rays trigger synthesis in skin)
Dietary sources: fatty fish, egg yolks, fortified milk, and supplements
Step 3: Diseases caused by vitamin deficiencies.

Vitamin D deficiency: Causes rickets in children and osteomalacia in adults. Both conditions involve softening and weakening of bones due to impaired mineralization.
Vitamin B1 (Thiamine) deficiency: Causes beriberi, affecting the nervous and cardiovascular systems.
Vitamin C deficiency: Causes scurvy, characterized by bleeding gums, joint pain, and poor wound healing.
Vitamin A deficiency: Can cause night blindness and, in severe cases, complete blindness.
Step 4: Analysis of each option.

(A) Beriberi: Incorrect. Beriberi is caused by vitamin B1 (thiamine) deficiency.
(B) Scurvy: Incorrect. Scurvy is caused by vitamin C deficiency.
(C) Rickets: Correct. Rickets is caused by vitamin D deficiency in children, leading to soft, weak bones, bowed legs, and skeletal deformities.
(D) Blindness: Incorrect. While vitamin A deficiency can cause night blindness and eventually complete blindness, vitamin D deficiency does not directly cause blindness.

Final Answer: (C) Rickets.
