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