The correct answer is the third option: Compared to students who took a test in a normal temperature room, test-taking students in a ninety-degree room were more likely to express hostility toward a stranger.

Explanation:

This option is correct because unlike the other options, it seems like an actual experiment has been conducted to investigate the effects of excessive heat on aggression. This can be inferred because there were two groups- a control group (students in a normal temperature room) and a group subject to the independent variable (students in a ninety-degree room). The result of this investigation provided evidence that excessive heat causes greater aggression.

The other options are too broad and general to gather evidence about excessive heat causing greater aggression.
