The primary function of the nail bed is to supply nutrients to the nail. The nail bed is the area of skin beneath the nail, and it is rich in blood vessels and connective tissue. This vascular supply plays a crucial role in promoting nail growth and health, as the nail bed provides oxygen and essential nutrients that help maintain the vitality of the nails.

The other options are related to the nail's function and aesthetics but do not accurately define the primary role of the nail bed. For example, while the nail polish rests on the nail plate, the nail bed itself does not provide a base for polish application; that is the function of the nail plate. Additionally, the shape of the nail is primarily determined by the underlying matrix and the structure of the nail itself, rather than the nail bed. Lastly, while the fingertips require some protection from the nails, the primary protective function is more closely associated with the nail's structure as a whole rather than being a specific role of the nail bed itself.
