Explanation:

- The phrase "Following detailed deliberations, the meeting has been ______ till next week" suggests a temporary postponement rather than a permanent one.

- Option 1: Proposed - This doesn't fit as it involves suggesting a plan or idea, not rescheduling.

- Option 2: Reviewed - This refers to examining something carefully, which doesn't match the context of delaying a meeting.

- Option 3: Adjourned - This means to suspend proceedings to a later time, fitting the idea of continuing the meeting next week.

- Option 4: Cancelled - This implies the meeting will not happen, conflicting with the notion of it being moved to next week.
