The answer to the question is e. The expected duration (time) of participation is not included in an informed consent statement. An informed consent statement is a document that provides potential research participants with information about the research study, including its purpose, procedures, risks, benefits, and their rights as participants. The statement should also inform participants that their participation is voluntary and that they have the right to withdraw from the research project at any time. The statement should be written in clear and understandable language and should be presented to participants before they agree to participate in the study. The expected duration (time) of participation is not typically included in an informed consent statement, although it may be provided to participants as part of the study information.
