The correct answer is Dissuade. The word "urge" means to strongly recommend or persuade someone to do something, or to drive them forward with encouragement or insistence. Therefore, its antonym should express the opposite action: convincing someone *not* to do something. "Dissuade" perfectly fits this definition, meaning to persuade someone against an action or belief, or to deter them from a course of action. It directly counters the act of urging by advocating for the opposite outcome.
Option B, Push, is incorrect because it is often synonymous with "urge" in the context of influencing someone. To "push" someone to do something means to compel or motivate them, aligning with the meaning of "urge" rather than opposing it.
Option C, Incite, is incorrect. "Incite" means to encourage or stir up (especially violent or unlawful behavior). This is a strong form of urging, often with negative connotations, and is clearly not an antonym for "urge"; rather, it is a type of urging.
Option D, Encourage, is incorrect. "Encourage" means to give support, confidence, or hope to someone, or to persuade them to do something. This meaning is very similar to "urge" and functions as a synonym or a closely related concept, not an antonym.
