Which of the following is a synonym for "comprehensive"?

The term "comprehensive" refers to something that is all-encompassing or covers a wide range of subjects or details. Therefore, a synonym for "comprehensive" would be a word that conveys the notion of being thorough or exhaustive.

The choice "thorough" is indeed a synonym for "comprehensive" because it implies a deep and complete approach to a subject, leaving no significant detail overlooked. A thorough examination, for instance, means that every aspect has been carefully considered.

In contrast, the other options do not convey a similar meaning. "Incomplete" suggests a lack of fullness or missing parts, "superficial" implies a concerning focus on surface-level details without depth, and "limited" denotes restrictions or a narrow scope, all of which are antithetical to the idea of comprehensiveness. Thus, "thorough" aligns perfectly with the essence of "comprehensive."
