Which of the following best defines the term "literature review"?

The term "literature review" is best defined as a comprehensive review of existing studies on a topic. This process involves collecting, analyzing, and synthesizing previous research findings to provide a thorough understanding of the current state of knowledge regarding a specific subject. A literature review serves several important purposes: it identifies gaps in the existing research, highlights relevant theories, and situates a new study within the broader context of academic discourse.

This approach allows researchers and scholars to assess what is known and what needs further exploration, thus informing the direction of future research. Conducting a literature review is a foundational aspect of many research projects, as it helps to ensure that new studies build upon previous work and contribute meaningfully to the field.
