Explanation

Vitamin D is an important nutrient that our body needs to stay healthy. If we don't get enough vitamin D, we may develop certain health problems. This question is asking about the deficiency of vitamin D and what health problem it can cause. The options are scurvy, pellagra, rickets, beriberi, and polio. Out of these options, the correct answer is rickets. Rickets is a condition that affects the bones, making them weak and soft. It is caused by a lack of vitamin D, which is needed for the body to absorb calcium and build strong bones. To prevent rickets and other health problems caused by vitamin D deficiency, it is important to get enough vitamin D from our diet or from sunlight. Foods that are rich in vitamin D include fatty fish, egg yolks, and fortified milk and cereal. Spending time outside in the sun can also help our body produce vitamin D. In summary, the deficiency of vitamin D can lead to health problems, including rickets which affects our bones. To prevent such problems, we should ensure we get enough vitamin D from our diet and/or sunlight.
