Four parts of the human body have been listed, out of which three are alike in some manner and one is different. Select the odd one.

Correct option is D

The odd one out, let’s analyze the characteristics of each body part:
(a) EYES: A sensory organ used for vision.
(b) NOSE: A sensory organ used for smell.
(c) EARS: A sensory organ used for hearing.
(d) HAIR: Does not function as a sensory organ; primarily serves for protection and regulation.
Explanation: The eyes, nose, and ears are all sensory organs with specific functions related to perception (sight, smell, and hearing). Hair, on the other hand, is not a sensory organ and serves a different function.
Correct answer the odd one is (d) HAIR.
