Bacteria provides vitamins to humans
Explanation:
The correct answer would be that bacteria provides vitamins to humans.
<u>By definition, mutualism is a type of symbiotic relationship between two organisms in which both benefit from each other.</u>
Bacteria in the gut of humans that provides vitamins to humans also benefit by making the human gut their shelter. While the vitamins represent an important nutrient to humans for their proper functioning, the shelter is also necessary for the bacteria for their safety.

Explanation:
Vitamin D is the vitamin that can be synthesized by the human body itself therefore it is not an essential vitamin for human beings. Human skin is the part that helps in making this vitamin in humans.
The natural form of vitamin D is vitamin D3 which is formed by the sunlight exposure on the skin. When we expose our skin in the sunlight the UV radiation penetrated our skin and converts provitamin D3 into pre-vitamin D3 then this previtamin can be isomerized into the natural form of vitamin D Which is vitamin D3. So the right answer is vitamin D.
