What is the nail root?

Part of the nail plate extending over the tip
The base of the nail inside the mantle
The visible portion of the nail
The fold of skin overlapping the sides

The correct answer is: The base of the nail inside the mantle

The nail root is the base of the nail that is located underneath the cuticle and cuticle beds. It is responsible for the production of nail cells and is connected to the nail matrix, which is responsible for the actual growth of the nail. Options A, C, and D are incorrect because they describe different parts of the nail, such as the visible portion, the tip, and the folds of skin around the sides. These parts are not considered the nail root, which is specifically the base of the nail inside the mantle. Therefore, option B is the most accurate and complete answer.
