Rickets in children and osteomalacia in adults are deficiency diseases of vitamin D.
Vitamin D is a nutrient that is essential for maintaining healthy bones and teeth. It helps the body absorb and use calcium, which is a key component of bone tissue. When the body doesn't get enough vitamin D, it can lead to a deficiency, which can cause the bones to become weak and brittle.
Rickets is a condition that affects children and is characterized by soft, weak bones, deformities, and muscle weakness. It is typically caused by a deficiency of vitamin D and calcium, which can be caused by a lack of exposure to sunlight, a diet low in vitamin D-rich foods, or certain medical conditions that affect the body's ability to absorb vitamin D.
Osteomalacia is a similar condition that affects adults, and it is also caused by a deficiency of vitamin D and calcium. It causes the bones to become weak and brittle, and it can lead to muscle weakness, bone pain, and an increased risk of fractures.
Therefore, the correct answer is option (b) "Vitamin D."
