Answer:
Scholarly materials: include information on the researcher's process or methods.
Step-by-step explanation:
Scholarly materials or sources are also known as academic, refereed or peer-reviewed sources. As those names suggest, scholarly materials are written by academics or experts in a certain field. They are supposed to be peer-reviewed in order to be validated. They must contain citations as a form of evidence when mentioning literature and other sources. They tend to have more sober visuals, since their purpose is to inform instead of to entertain or attract the general audience. Finally, they must include information on the researcher's process or methods. As we can see, we can eliminate the first three options and choose the last one as the correct answer.
