CVitamin D
DVitamin E
Correct Answer: Vitamin DYour Answer: C
✅ Correct Answer: C — Vitamin D
Vitamin D (specifically its active form Calcitriol) is essential for calcium absorption from the intestine into the bloodstream. Without adequate Vitamin D, the intestine cannot absorb sufficient calcium, leading to low blood calcium levels, which causes Rickets in children (soft bones) and Osteomalacia/Osteoporosis in adults. Vitamin D is synthesized in skin when exposed to sunlight (UV rays).
❌ Why other options are wrong:
• A. Vitamin A — Vitamin A is essential for vision (rhodopsin production), skin health, and immune function; not for calcium absorption.
• B. Vitamin B12 — Vitamin B12 is important for red blood cell formation and nervous system function; not for calcium absorption.
• D. Vitamin E — Vitamin E is an antioxidant that protects cell membranes; not for calcium absorption.
📝 Important Note: Vitamin D = 'Sunshine Vitamin' synthesized by skin from sunlight. Vitamin D deficiency = Rickets (children), Osteomalacia (adults). Calcium absorption requires Vitamin D. Dairy products and fortified foods are good sources. SSC CGL frequently tests vitamin-deficiency diseases.
