Correct answer is (a) leydig cells

Explanation: The growth, maintenance and functioning of secondary sex organs (epididymis, vasa deferentia, accessory glands and penis) are under the control of testosterone hormone secreted by Leydig’s cells of testis, while those of seminiferous tubules and Leydig’s cells are controlled by Follicle Stimulating Hormone (FSH) and Interstitial Cells Stimulating Hormone (ICSH) of anterior pituitary lobe respectively.
