Which of the following best describes a "comprehensive" approach?

A "comprehensive" approach is characterized by its all-encompassing nature, meaning it considers all relevant parts and perspectives of a subject matter. When something is described as comprehensive, it implies that every aspect is included, leaving no significant detail overlooked. This thoroughness ensures a complete understanding and evaluation of the topic at hand.

In contrast, focusing on a single aspect, involving only essential details, or limiting information to specific areas all suggest a narrowed scope, which is contrary to the definition of "comprehensive." Such limited approaches might miss crucial information or broader contexts that could be essential for a full understanding. Therefore, the best descriptor of a "comprehensive" approach is one that includes everything in a complete manner.
