Correct option is A
The correct answer is (a) Rickets.
· Rickets is a childhood bone disorder primarily caused by a deficiency of vitamin D, calcium, or phosphate.
· These nutrients are essential for proper bone development and mineralization.
· When there is a deficiency, it leads to soft, weak bones, poor growth, bone pain, and an increased risk of fractures.
· In severe cases, rickets can result in bone deformities such as bowed legs, knock knees, and a protruding breastbone.
· Vitamin D deficiency is often the main culprit behind rickets.
· Vitamin D is synthesized in the skin upon exposure to sunlight and is also obtained from dietary sources such as fortified foods, fish oils, and supplements.
