Which word is defined as "generally accepted, having superior power"?

The word that means "generally accepted, having superior power" is "prevailing." This term is often used to describe opinions, conditions, or practices that are dominant or widely recognized in a particular context. In this sense, prevailing indicates that something holds sway or influence over others, reflecting its acceptance or superiority. For instance, the prevailing attitude in a society can dictate social norms and behaviors, demonstrating its power in shaping how people think and act.

The other options do not convey that specific meaning. For instance, "mundane" refers to things that are ordinary or commonplace, lacking in excitement or uniqueness. "Arrogance" denotes an attitude of superiority or self-importance, but it does not imply general acceptance. "Trite" describes something that is overused or lacking originality, making it far from a term that suggests acceptance or power. Thus, "prevailing" is the most fitting choice for the definition provided.
