Knowledge of the hypothesis may bias the participants' behaviour, which can affect the results of the study. Therefore, researchers may not adequately inform participants of the purpose of the study to avoid bias, which can compromise informed consent. The other options are not accurate because informed consent is essential in research to protect participants' rights and ensure their safety. It does not take an excessive amount of time, participants' lack of interest is not an issue, and follow-up studies can still be conducted with informed consent.
