Answer
(c) Three treatments
Work Step by Step
The factors are variables whose levels are manipulated by the experimenter.
FACTORS = type of bee hive (active/nonactive/no)
A matched pairs experiment compares two treatments which each subject undergoes.
NOT MATCHED, because there are three treatments instead of two.
Stratified random sampling draws simple random samples from independent subgroups.
NOT STRATIFIED BY BEEHIVE
Thus, we then know that answer (c) is correct since the three treatments are an active beehive, nonactive beehive, and no behave.
