• A. Ovary
• B. Testis
• C. Kidney
• D. None of these

Hint:

Leydig cells in testes are the main source of testosterone in males.

Answer 1

The Correct Option is B

Step 1: About Testosterone:
Testosterone is the primary male sex hormone responsible for the development of male reproductive tissues and secondary sexual characteristics (e.g., facial hair, deep voice, muscle growth). Step 2: Organ of Secretion:
In males, it is secreted by the Leydig cells present in the testis.
In females, ovaries secrete small amounts of testosterone, but in very low concentration.
Step 3: Other Options:
Ovary → secretes estrogen and progesterone (female hormones).
Kidney → secretes erythropoietin, not testosterone.
Step 4: Final Answer:
Testosterone is secreted by the Testis.
