Answer 1

Answer: (D)

Osteomalacia is softening of the bones, typically through a deficiency of vitamin D.
Osteoporosis causes bones to become weak and brittle so that a fall or even mild stresses like bending can cause a fracture. It is caused by a long-term deficiency of calcium and is more common in adult women.
Rickets is caused by a deficiency of vitamin D, calcium or phosphate.
Keratomalacia is an eye disorder that results from vitamin A deficiency.
Therefore, the correct answer is option B.
