Answer:
c. This research would be eligible for exemption because the researcher is not interacting with the children and the playground is a public setting.

This is the answer that best describes the scenario. The IRB review is a mechanism that is designed to deal with the moral and ethical implications of research. However, in this case, this is not applicable. The main reason is that the children will not be contacted or damaged in any way. They also will have their privacy protected fully. The researcher, moreover, attempts to conduct this at a playground, which is a public setting.
