D. Vitamin B12
E. None of above

Check Answer

The correct answer is B) Vitamin D.

The human body can obtain vitamin D through sun exposure, specifically through the process of sunbathing. Vitamin D is a fat-soluble vitamin that is unique in that the human body can produce it when the skin is exposed to ultraviolet (UV) rays from the sun. Vitamin D is also called the “sunshine vitamin” because of this ability of the body to make it through sun exposure.

Vitamin D is essential for maintaining healthy bones and teeth, as it helps the body absorb calcium and phosphorus, which are the main building blocks of the bones. It also plays a role in the body’s immune system, regulating the growth and differentiation of cells, and has been linked to a number of other health benefits, including reducing the risk of certain types of cancer, diabetes, heart disease and certain autoimmune conditions.

It’s worth mentioning that, excessive sun exposure can cause skin damage and increase the risk of skin cancer, so it’s important to use sunscreen and limit exposure to the sun during the hours when its rays are the strongest (typically 10am to 4pm). Additionally, certain populations, such as those with darker skin, older adults, and people with certain medical conditions, may have a harder time producing enough vitamin D from sun exposure and may need to get it through diet or supplements.
