Answer Details

The correct option that best completes the sentence is "than". "No sooner" is an expression used to show that one event happens immediately after another event. In this sentence, Uche's arrival at the meeting is the first event, and the second event is the beginning of the proceedings. The word "than" is used to connect the two events and indicate that the proceedings began immediately after Uche's arrival. Therefore, the correct answer is option A, "than". The other options do not fit grammatically or convey the same meaning in the given context.
