Which deficiency signs are commonly associated with vitamin C deficiency?

• A. Night blindness.
• B. Scurvy features such as gum bleeding and poor wound healing; fatigue is also typical.
• C. Increased thirst.
• D. Hypocalcemia.

Answer: (B)

Vitamin C is essential for collagen synthesis, so without it connective tissues weaken. This leads to classic signs of deficiency: gums that bleed, poor wound healing, and symptoms like fatigue from impaired tissue repair and vascular integrity. Night blindness isn’t related to vitamin C—it's a hallmark of vitamin A deficiency. Increased thirst points to other issues such as dehydration or diabetes, and hypocalcemia relates to calcium/vitamin D metabolism, not vitamin C.
