What possible inference might the audience draw if the size of the meeting room is too large as compared to the number of attendees? The meeting is a failure as the size of the room was inappropriate to entertain such a small group of people. The meeting is a failure as the size of the room illustrates the lack of advanced planning. The meeting is a failure as it could not attract the expected number of people. The meeting is a failure as the organizer failed to book a room of the right size.

The correct answer is letter "C":  The meeting is a failure as it could not attract the expected number of people.

Explanation:

Entering a large conference room and seeing a few people seated is a clear sign that the meeting is a failure since the speaker or the reason for the meeting was not good enough to attract the expected amount of people. This situation could also imply that the organizers set their expectations too high for the meeting without researching the potential number of people interested in attending the reunion.
