Assertion (A): The testes are situated outside the abdominal cavity within the scrotum.

Reason (R): Scrotum helps to maintain the lower temperature of testes by 2°C for normal spermatogenesis.

Options

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.
