- A is True and R is False
- A is False and R is True
- Both A and R are True
- Both A and R are False
Answer
A is False and R is True
Reason — Seminal vesicles secrete an alkaline fluid, but semen does not pass through the ureter. The ureter is part of the urinary system, carrying urine from the kidneys to the bladder, it is not related to the reproductive pathway. Semen passes through the ejaculatory duct and urethra, not the ureter.
