Step-by-step explanation:
The synonyms provided in the question are top, crest, and peak. When looking up these terms in a thesaurus, they all point to a similar meaning of the highest point or summit of something. However, the term that matches the given synonyms precisely is peak.
As a noun, peak denotes the highest point, such as the summit of a mountain. In a sentence: After a challenging ascent, the mountaineers were elated to stand on the peak, observing the breathtaking panorama spread out beneath them. The verb form of peak indicates reaching the highest point or maximum level. For instance: The athlete's performance peaked during the championship game, where she scored the winning goal.
In contrast, the word peek means to look at something quickly and often secretively. An example sentence could be: The child couldn't resist the urge to peek at the presents hidden under the Christmas tree. Finally, pique in its verb form means to stimulate interest or curiosity, as in: The mystery novel piqued my interest from the first page. The noun form of pique represents a feeling of irritation: She could not hide her pique when her suggestions were ignored during the meeting.
