Find the odd number / letters / word from the given alternative:

See : Eye
Hear : Ears
Smell : Nose
Touch : Skin E. Tongue : Taste

The odd one out is option E. Tongue : Taste.

The other options are all pairs of senses and the organs that are used to perceive them. Sight is perceived by the eyes, hearing is perceived by the ears, smell is perceived by the nose, and touch is perceived by the skin. Taste is perceived by the tongue, but it is not a sense that is as closely linked to a specific organ as the others. The tongue is involved in taste, but it is not the only organ that is involved. The nose is also involved in taste, as it helps to detect the aromas of food. Additionally, the brain plays a role in taste, as it interprets the signals that are sent from the tongue and the nose.

Therefore, the odd one out is option E. Tongue : Taste.
