When was the tennis match rescheduled?

The notion that the tennis match was called off implies that it was not able to proceed as originally planned, leading to a situation where rescheduling becomes necessary. The phrasing suggests that there was an event or circumstance that prevented the match from occurring, thereby establishing the context for why a reschedule would be required.

The other options convey different meanings. Saying "it wasn't needed" indicates that there was no change necessary, while "it will be rescheduled" implies that the match has not yet been rescheduled, contradicting the original question. The term "it was avoided" suggests that the match never happened but does not affirm that it will be rescheduled. Therefore, “it was called off” effectively communicates that the match was indeed cancelled, which aligns directly with the inquiry about the need to reschedule.
