Step 1: Meaning of concurrence.
The word “concurrence” comes from the Latin \textit{concurrere} meaning “to run together.” It refers to agreement in opinion, simultaneous occurrence of events, or consensus.
Step 2: Checking each option.
- (A) Agreement — synonym of concurrence.
- (B) Accord — also means agreement, hence synonym.
- (C) Consensus — directly means general agreement, thus matches.
- (D) Coincidence — concurrence also means simultaneous occurrence, so this is valid.
- (E) Harmony — while related to peace and balance, it refers more to a pleasing arrangement rather than agreement or simultaneous action. This is not a strict synonym of concurrence.
Step 3: Final Answer. The only option not matching is Harmony.
