How is someone described if they are 'erudite'?

The term 'erudite' is derived from the Latin word 'eruditus,' meaning 'instructed' or 'educated.' It refers to someone who possesses deep, extensive knowledge, especially acquired through reading and studying. An erudite individual has a comprehensive understanding of various subjects and demonstrates intellectual depth that often goes beyond surface-level comprehension. This makes the choice that refers to 'having profound knowledge' the most fitting description.

In contrast, the other options indicate a lack of understanding or education, which is the opposite of what it means to be erudite. Those descriptions suggest ignorance or a deficiency in knowledge, highlighting that erudition inherently implies an abundance of information and insight.
