The correct answer is an experimental study with one independent variable.
This study is an experimental study because it involves investigating a causal relationship between two phenomena. In this study the researcher is investigating the relationship and checking for causality between the size of a group, and its effect on conformity behavior. This study furthermore has an independent variable (i.e. a variable that is manipulated and controlled) which is the size of the group of people staring up at a window.
A similarity between them is that they are all elected officials that have experience of appointed government bodies and are expected to do well.
a difference is that a commission government body is typically a lower amount of people, around 5 people. a council would be around 20 people.
Hope this helps you.
