Prepare a list of some animals that are found parasitic on human beings.
Assertion (A): All flatworms are endoparasites found in animals including human beings. Reason (R): Flatworms have specialized adaptations for parasitic life including hooks and suckers.
Correct answer: D — If the assertion is false but the reason is true.
NCERT states “These are mostly endoparasites found in animals including human beings” - the qualifier “mostly” indicates exceptions exist like free-living Planaria. The Assertion removes this qualifier making it false. The Reason is independently true from NCERT describing parasitic adaptations, but the Assertion is false due to existence of free-living flatworms.
