Solution

The correct option is D A-Sertoli cells, B-Spermatogonia, C-Interstitial cell, D-Sperms
The testis consists of seminiferous tubules that consist of Sertoli cells that provide nutrition to the germ cells and these cells are lined on the inside along with Spermatogonia or the male germ cells. The regions towards the outside (interstitial spaces) contain interstitial cells. The matured spermatogonia are the spermatozoa or sperms that are present in the interior of the seminiferous tubule.
So, the correct option is 'A-Sertoli cells, B-Spermatogonia, C-Interstitial cell, D-Sperms'.
