Four pairs have been given, out of which three are alike in some manner and one is different. Select the odd one.

Correct option is D

(a) Birds : Chirp: This pair represents birds and the sound they make, which is "chirp." It follows the pattern of animal-sound relationships.
(b) Snakes : Hiss: This pair represents snakes and the sound they make, which is "hiss." It also follows the animal-sound relationship.
(c) Lion : Roar: This pair represents lions and the sound they make, which is "roar." It fits the same pattern as the previous pairs.
(d) Dogs : Coop: This pair is different because "coop" refers to a shelter or enclosure, typically for chickens, not a sound that dogs make. The correct sound associated with dogs is "bark." Hence, this pair does not match the animal-sound relationship followed by the other options.
So, option (d) is the odd one out.
