What does a deficiency of Vitamin D cause in adults?

Osteoporosis
Osteomalacia
Rickets
Scurvy

The correct answer is: Osteomalacia

A deficiency of Vitamin D in adults can cause a condition called Osteomalacia, which is the softening of bones due to a lack of mineralization. Osteoporosis (option A) is a different condition that mainly affects older adults and is characterized by reduced bone density and an increased risk of fractures. Rickets (option C) is a condition that primarily affects children and is caused by a deficiency of Vitamin D, resulting in weak and soft bones. Scurvy (option D) is caused by a deficiency of Vitamin C and is characterized by symptoms such as weakness, anemia, and gum disease, but it does not affect bones. Therefore, Osteomalacia is the only option that accurately describes the consequence of a Vitamin D deficiency in adults.
