Explanation:

Seminiferous tubules are the site of sperm production (spermatogenesis). Spermatogonia are the germ cells that undergo spermatogenesis. Sustentacular cells (Sertoli cells) provide support and nourishment to the developing sperm cells. Interstitial cells (Leydig cells) are located outside the seminiferous tubules and produce testosterone.

Answer:

D. Both spermatogonia and sustentacular cells
