What action does "terminate" refer to?

The term "terminate" specifically refers to the action of bringing something to an end or concluding it. In various contexts, such as in legal agreements, employment, or projects, to terminate indicates a decisive point where the ongoing action or contract is officially closed or finished. This aligns with the meaning of the word, which conveys the idea of stopping something that has been in progress.

Meanwhile, the other options suggest actions that are the opposite of termination. "Extend indefinitely" implies prolonging a situation, "start anew" focuses on initiating something fresh, and "prolong the process" suggests lengthening the duration of an ongoing task. Each of these contrasts with the concept of bringing something to a closure or end, reinforcing the correctness of identifying "bring to an end" as synonymous with "terminate."
