How is the term "ambiguous" best described?

The term "ambiguous" is best described as having multiple meanings. This reflects a condition where something, such as a statement or situation, can be understood or interpreted in more than one way. Ambiguity often arises in language or communication when the context does not clarify the intended meaning, leaving room for various interpretations. This can lead to confusion or misunderstanding, as the audience may not know which definition or perspective is intended.

In contrast, the other options suggest clarity and singularity in interpretation, which directly contradicts the essence of ambiguity. Therefore, the definition that captures the multifaceted nature of "ambiguous" is indeed the one that describes it as having multiple meanings.
