Answer:
The correct answer is A. Explaining the hypothesis to the participants.
Explanation:
Informed consent means getting the permission (consent) of a participant for a clinical trial, therapy, experiment or research, amongst other. It is an informative document which allows the individual to be a part of an investigation and by signing it, he/she allows the researcher to use the information given as well as consenting to it.
During the informed consent, the participants understand that their <em>participation is </em><em>voluntary</em>, they sign or the guardian signs (if the participant is a minor) and they understand that the information will be confidential.
The researcher, however, <em>does not have to explain the hypothesis to the participants</em> in the informed consent since the hypothesis is a part of the investigation and does not provide much information for the participants.
