Choose the word which is different from the rest.

The answer is D. Laugh.

The other three words, cry, sob, and weep, all refer to the act of shedding tears. Laugh, on the other hand, refers to the act of making a series of short, sharp, typically high-pitched sounds expressing amusement, pleasure, or derision.

Cry is the most general of the four words, and can refer to shedding tears for a variety of reasons, such as sadness, happiness, or pain. Sob is a more specific word that refers to crying with deep, convulsive breaths. Weep is also a more specific word that refers to crying with tears streaming down one’s face. Laugh is the only word of the four that does not refer to crying.
