Elaborating a research project, the academic must pay attention to the mandatory items, both in the process and on paper. The obligation of these items is linked to the need for clarity, objectivity, organization, systematization, among other things, that must be present in research. However, there are also optional items, and it will depend on the researcher's choice whether or not to use them. Choose the CORRECT alternative that presents an item that is optional in the research project:


A methodology.
References.
The hypothesis.
The literature review.
