Answer: C

Sertoli cells, also known as nurse cells or sustentacular cells, are specialized cells that are present in the seminiferous tubules of the testes. These cells play a crucial role in supporting the development and maturation of spermatozoa. However, they are not reproductive cells themselves. Instead, Sertoli cells are known as protective cells, as they provide a variety of essential functions that support the development and survival of germ cells.
Some of the functions of Sertoli cells include providing nutrients to developing spermatozoa, regulating the exchange of substances between the bloodstream and the seminiferous tubules, producing anti-Müllerian hormone, and phagocytosing apoptotic germ cells. Additionally, Sertoli cells secrete a variety of factors that help to maintain the blood-testis barrier and support the proper development of the spermatozoa.
In summary, Sertoli cells are a type of supportive cell that is essential for the proper development and maturation of spermatozoa. They are not reproductive cells themselves, but rather provide a variety of functions that support the survival and development of germ cells. Therefore, the correct answer is option C, protective cells.
