What does the term 'extraneous' signify?

The term 'extraneous' signifies something that is not pertinent or relevant to the matter at hand. It refers to elements that are unnecessary or unrelated, often implying that they can be excluded without affecting the core topic or issue. For example, in a discussion about a specific event, any information that does not contribute to understanding that event could be described as extraneous.

The other options suggest meanings that align with being essential or relevant, which contrasts with the definition of 'extraneous.' Therefore, 'not pertinent or relevant' accurately captures the essence of what it means to be extraneous, highlighting its role in distinguishing between what is necessary and what is superfluous in a given context.
