Question 23

Infants have a high metabolic rate and rapid growth, so their energy requirement per unit body weight is the greatest compared to other life stages. So the statement is true.

Rickets is a bone disorder that occurs due to a deficiency of Vitamin D (which helps in calcium absorption for bone health). Vitamin A is for vision/immune, Vitamin K for blood clotting, Vitamin C for collagen. So the correct option is Vitamin D.
