AIIMS 2017 Zoology Excretory System Assertion Reason Question
Read the Assertion and Reason carefully to mark the correct option from those given below Assertion Urinary bladder is lined by transitional epithelium. Reason Transitional epithelium keeps the size of the urinary bladder constant at all time.
Both Assertion and Reason are true and Reason is the correct explanation of Assertion
Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
Assertion is true but Reason is false
Both Assertion and Reason are false
Correct Answer
Detailed Explanation
Option B is correct because the assertion that the urinary bladder is lined by transitional epithelium is true; this specialized epithelium allows for stretching and accommodates varying volumes of urine. However, the reason provided is false; while transitional epithelium enables the bladder to expand and contract, it does not keep the size of the bladder constant at all times, as the bladder's size changes with urine volume. Option A is incorrect because, although both statements are true, the reason does not explain the assertion. Options C and D are incorrect as they misrepresent the truth of the assertion regarding the bladder's lining.
