The correct answer is C. Both.
If a member disagrees with the reasons of the joint note of an accident, he may give a dissent. A dissent is a formal statement of disagreement with the majority opinion of a court or other body. It is typically written by one or more judges who disagree with the decision of the court, and it sets forth their reasons for disagreeing.
In the context of an accident, a dissent might be written by a member of a joint investigation team who disagrees with the team’s conclusions about the cause of the accident. The dissent might set forth the member’s own theory about the cause of the accident, or it might simply point out flaws in the team’s investigation.
A dissent is not a binding decision, but it can be influential. It can help to shape public opinion about the accident, and it can also be used as evidence in future legal proceedings.
The other options are incorrect. Option A, accident, is not a correct answer because it is not a type of document that can be submitted by a member who disagrees with the reasons of the joint note of an accident. Option B, dissent, is not a correct answer because it is not the only type of document that can be submitted by a member who disagrees with the reasons of the joint note of an accident. Option D, none of these, is not a correct answer because it is not a possible answer to the question.
