Which of the following is a fat-soluble vitamin that helps in promotion of calcium absorption in the gut for bone health?
Vitamin D
The four fat-soluble vitamins are A, D, E and K. Among these, Vitamin D (calciferol) is the one directly linked to calcium metabolism.
Vitamin D promotes the absorption of calcium (and phosphate) from the intestine (gut) into the blood. This maintains the calcium levels needed for the mineralisation and strength of bones and teeth. Its deficiency causes rickets in children and osteomalacia in adults.
Vitamin A is fat-soluble but supports vision and the immune system; Vitamin C (ascorbic acid) and the Vitamin B complex are water-soluble, so they do not fit the "fat-soluble" requirement.
Hence, the fat-soluble vitamin that promotes calcium absorption in the gut is Vitamin D.
