Which of the following best defines "acclaim"?

The best definition of "acclaim" is that it refers to the act of praising something enthusiastically. This term conveys a sense of strong approval and admiration, often in a public setting. When something or someone receives acclaim, it suggests not only that there is praise, but that it is delivered with a significant level of enthusiasm and recognition.

The other options do not capture this intensity and context that "acclaim" carries. While praising something might relate closely, it lacks the specific emphasis on enthusiasm. Likewise, giving consent and making something beautiful do not align with the meaning of "acclaim" at all, as they refer to completely different actions and concepts.
