Answer:
B) between the seminiferous tubules
Explanation:
The interstitial endocrine cells which produce testosterone are called Leydig cells (interstitial cells of Leydig). The function of these cells is to release androgen hormones like testosterone, dehydroepiandrosterone (DHEA) and androstenedione.
Different seminiferous tubules are surrounded by basal lamina and the clusters of the Leydig cells in interstitial compartment between each seminiferous tubules.
