Answer:
The correct answer is letter "C": greater than.
Step-by-step explanation:
If the supply of chairs for a class is the same at 10:00 a.m. and noon, but there is a shortage of seats at 10:00 a.m., it implies more students prefer to attend that class at 10:00 a.m. In other words, the demand for the class at 10:00 a.m. is greater at that time than at 12:00 p.m.
