Which term is used for a vote that occurs when all are in agreement?

Unanimous consent is the term used to describe a situation where everyone in the group agrees on a matter. It indicates that there is complete agreement among the members present, which allows the group to proceed with the business without the need for a formal vote. This method is often utilized in meetings to expedite decision-making when there is obvious consensus, as it streamlines the process and avoids unnecessary delays associated with formal voting procedures.

In contrast, the other terms do not signify complete agreement among all members. A majority vote requires more than half of the members to agree for a decision to be made, while a plurality vote simply means the choice with the most votes wins, even if it does not reach a majority. Consensus opinion often implies broad agreement but might not necessarily mean that every individual fully endorses the decision, which distinguishes it from unanimous consent. The definition and context of unanimous consent make it the correct choice for a vote that occurs when all are in agreement.
