The correct option is C Interstitial cells or cells of Leydig
Leydig cells or interstitial cells are present in testes. These cells lie between the seminiferous tubules and produce testosterone in the presence of luteinizing hormone.
Leydig cells release a class of hormones called androgens, i.e., they secrete testosterone, androstenedione and dehydroepiandrosterone.
Thus, the correct answer is option A.
