B) a group of rats that are put in the same aversive situation, but who are allowed some control over the aversive situation

Including a group of rats who are put in the same aversive situation but who have some control over the aversive event will allow for a clear comparison between rats who experience learned helplessness and rats who do not. This control group will make it clear whether it is the aversiveness of the event or lack of control that leads to learned helplessness in the experimental group. The other options (A, C, and D) do not provide a relevant control group.
