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

Correct option is D

The correct answer is (d) Tongue
The throat, nose, and mouth are passageways or cavities involved in the respiratory and digestive systems. They primarily function as channels for air, food, and fluids. On the other hand, the tongue is a muscular organ with specialized functions, including taste sensation, speech, and aiding in swallowing. This makes the tongue structurally and functionally different from the other three, making it the odd one out.
Information Booster:
Throat: Part of the respiratory and digestive systems, acting as a passage for air and food.
Nose: Primary organ for smell and also filters and humidifies the air we breathe.
Mouth: Serves as the entry point for food and air, and is essential for speech.
Tongue: A muscular organ with taste buds, aiding in speech, food manipulation, and swallowing.

Additional Information

• The throat connects the mouth and nasal cavity to the esophagus and larynx.
• The nose filters, moistens, and warms the air before it reaches the lungs.
• The mouth plays a key role in mechanical digestion through chewing and the initial breakdown of food by saliva.
• The tongue is the only part in the list with muscle tissue as its primary structure, making it different from the other three.
