AIIMS 2018 Zoology Biology MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Which of the following is correct
A
Macropus– Ear pinna, body hairs, 4 chambered heart
B
Pavo–Long bones ossified, fore limbs modified to wings
C
Ichthyophis–covering on eyelids, Scales present
D
Limulus–chitinous exoskeleton, 3 pair of legs
Correct Answer
Option A
Detailed Explanation
The correct answer is A) Macropus, as it accurately describes features of marsupials, which have ear pinnae, body hairs, and a four-chambered heart. In contrast, Pavo (peacocks) have long bones ossified and modified limbs for flight, and Ichthyophis (a type of amphibian) do not possess scales but rather have smooth skin. Thus, option A is the only choice that correctly aligns anatomical traits with the appropriate animal group.
