Pick an option and check your answer. The full worked answer is below either way.
Answer
(A) is false and (R) is true.
Read the assertion word by word, because one word makes it false.
THE ASSERTION IS FALSE. Seminal vesicles do pour an alkaline secretion into the semen — but the semen passes through the URETHRA, not the URETER. The ureter carries urine from the kidney to the bladder and has nothing to do with semen at all.
THE REASON IS TRUE. The vagina is acidic (about pH 4) as a defence against infection, and that acidity would immobilise or kill sperms, so the alkaline secretions neutralise it.
So the assertion is false and the reason true — option (B).
THE TRAP is a single-letter difference that students read straight past because the rest of the sentence is correct: URETER — kidney to urinary bladder (urine only) URETHRA — bladder to outside; in the male it also carries semen In an assertion-reason question, check every noun. A statement that is 95% right is still false.
