The correct answer is C. Interstitial cells of the testis.
Explanation:
The testosterone is one of the main sex hormones in males, due to this, this hormone is linked to sexual characteristics as well as behavior, mass muscle development, among others. In terms of testosterone production, the production of testosterone occurs mainly on the testis (reproductive glands or gonads) and more specifically in the interstitial cells of these called Leydig cells which are specialized cells that besides producing testosterone produce androstenedione and dehydroepiandrosterone. Additionally, the production of any hormone in this cell is stimulated by the luteinizing hormone. According to tho this, it can be concluded testosterone is produced in the interstitial cells of the testis.
