which of the following activities constitutes engagement in research?

The activity that constitutes engagement in research is:

• Obtaining informed consent and conducting research interviews.

In human-subjects research guidance, an individual or institution is considered engaged when they:

• Intervene or interact with participants for research purposes (for example, conducting interviews or administering surveys).

• Obtain informed consent directly from participants for a research study.

By contrast, activities such as merely informing people that a study exists, handing out written information prepared by others, or asking permission to pass their contact details to a research team are usually classified as recruitment or referral activities and often do not themselves count as engagement in research under typical IRB/ethics guidelines.
