Final Answer :
B
Explanation :
A representative sample is a group of individuals that is similar to the population being studied in important characteristics such as age and sex. This helps to ensure that the findings of the study can be generalized to the larger population. A volunteer bias refers to the fact that individuals who volunteer to participate in a study may differ from the general population in important ways, and may not be representative. The experimental group is the group of individuals who receive a treatment in an experiment, while the control group is the group that does not receive the treatment, and is used as a comparison for the experimental group.
