• D. The progesterone produced by corpus luteum is biologically different from the one produced by placenta.

Answer 1

The correct option is A Testosterone is produced by Leydig cells under the influence of luteinizing hormone (LH).

In the male, luteinizing hormone promotes the development of the interstitial tissue (Leydig cells) of the testes and hence promotes the secretion of the male sex hormone, testosterone.
