AIIMS 2019 Zoology Insect Excretion MCQ Question
Assertion: Malpighian tubules are excretory organs in most of the insects
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Option B is correct because the assertion that Malpighian tubules are excretory organs in most insects is true; these structures play a crucial role in the excretion of nitrogenous wastes and the regulation of water (H₂O) and ion balance. However, the reason provided is not explicitly stated in the question, making it impossible to determine if it correctly explains the assertion, thus supporting the conclusion that while both statements are true, they are not directly linked.
Option A is incorrect because we cannot confirm the reason as a correct explanation without additional context. Option C is incorrect since the assertion is indeed true, and option D is incorrect as the assertion is valid.
