Taking part in the research is voluntary, but if you choose to take part, you waive the right to legal redress for any research-related injuries
Answer: Option A.
Explanation:
Exculpatory language is the language which removes or waives away the legal rights of the people who are about to take part in any events or participate in any thing.
A consent form or an informed consent should not include any kind of the exculpatory language which results in the waiving away of the legal rights of the people who are going to sign the form for taking part in an event, in any research and so on.
