Question

Accepted Answer

Disease caused by deficiency of Vitamin – C (Ascorbic acid) is Scurvy.

1. **Explanation for Option 3 (Scurvy):**
   Scurvy is a disease that results from a deficiency of Vitamin C, also known as ascorbic acid. Vitamin C is essential for the synthesis of collagen, which is a vital component of connective tissues in the body. Without adequate Vitamin C, the body cannot properly form collagen, leading to symptoms such as bleeding gums, joint pain, and fatigue. Historically, scurvy was common among sailors who did not have access to fresh fruits and vegetables during long sea voyages. The inclusion of citrus fruits in their diet was found to prevent and cure the disease, highlighting the critical role of Vitamin C.

2. **Explanation for why other options are incorrect:**

- **Option 1 (Night-blindness):** Night-blindness is primarily caused by a deficiency of Vitamin A, not Vitamin C. Vitamin A is crucial for maintaining healthy vision, and its deficiency can lead to difficulties seeing in low light or darkness.

- **Option 2 (Beri-Beri):** Beri-Beri is caused by a deficiency of Vitamin B1, also known as thiamine. This condition affects the cardiovascular and nervous systems, leading to symptoms such as weakness, pain in the limbs, and in severe cases, heart failure.

- **Option 4 (Rickets):** Rickets is a disease caused by a deficiency of Vitamin D, calcium, or phosphate. It leads to softening and weakening of the bones, primarily affecting children. Vitamin D is essential for the absorption of calcium and phosphate in the body.

In conclusion, Scurvy is the correct answer as it is directly linked to a deficiency of Vitamin C, while the other options are associated with deficiencies of different vitamins.
