Which word would best describe being in total agreement?

• A. Primary
• B. Fault
• C. Unanimous
• D. Perennial

Answer: (C)

The best word to describe being in total agreement is "unanimous." This term is commonly used to indicate that everyone involved is in complete accord or harmony regarding a decision, opinion, or belief. When a group is unanimous, it means there are no opposing views or dissenting opinions; everyone agrees completely.

In contrast, the other options do not convey the same meaning of complete agreement. "Primary" refers to something that is first or most important, rather than related to agreement. "Fault" pertains to an error or blame, which is contrary to the notion of consensus. "Perennial" describes something that is enduring or recurrent, typically used in relation to plants or concepts that persist over time, but it does not suggest agreement at all. Therefore, "unanimous" is the most appropriate choice to express the idea of total agreement.
