Answer:
(a) sertoli cells
Explanation:
In testicular lobule, each seminiferous tubule is made up of male germ cells (spermatogonia), Sertoli cells and lyeding cells. The male germ cells undergo meiotic divisions finally leading to sperm formation while Sertoli cells provide nutrition to the germ cells. The regions outside the seminiferous tubules, called as interstitial spaces, contain small blood vessels and interstitial cells or Leydig cells. Thus, the correct answer is option A.
