What action does the word "writhe" describe?

The word "writhe" describes a specific type of movement characterized by twisting or contorting. It typically refers to a physical motion that may suggest a struggle, discomfort, or intense emotion, often depicting someone or something moving in a painful or agitated manner. This aligns perfectly with the idea of moving in a twisting or contorted way, which captures the essence of what "writhe" conveys.

In contrast, staying motionless suggests no movement at all, while walking elegantly implies a smooth and graceful forward motion that is not twisting or contorting. Similarly, leaping forward indicates a more direct and unambiguous progression rather than the complex and often chaotic movement implied by "writhe." Thus, the action of writhing stands out clearly as a twisting or contorted movement, solidifying B as the correct choice.
