Select the most appropriate ANTONYM of the given word.

Escalate

Plunge

The correct answer is option 3. Plunge.

"Escalate" means to increase rapidly in extent or intensity, often in a negative sense such as conflict or tension

On the other hand, "Plunge" refers to a sudden decrease or decline, suggesting a rapid drop or decrease in intensity.

Therefore, "Plunge" is the antonym of "Escalate" as it represents the opposite action, indicating a sudden decrease or decline instead of an increase or intensification.
