What refers to any printed material used for research reference?a.Literatureb.Referencing Materialc.Review of Related Literatured.Research

The correct answer is option b. Referencing Material.

Here's a brief explanation of each option:

1. Literature - This typically refers to written works, especially those considered of superior or lasting artistic merit. While it can indeed include scholarly articles, it is broader than just research references.

2. Referencing Material - This specifically denotes printed or digital materials utilized for the purpose of referencing in research, making it the most precise term in this context.

3. Review of Related Literature - This is a specific section or chapter in a research paper that summarizes and analyzes previous studies relevant to the current research topic. It is not a type of material itself but rather a way to utilize such materials.

4. Research - This is a broad term that encompasses the systematic investigation into and study of materials and sources to establish facts and reach new conclusions, but it does not refer specifically to printed materials.

Thus, for the specific inquiry about materials used for research reference, Referencing Material is the most accurate choice.
