An Experiment Was Conducted to Compare Participant Responses to Two

An experiment was conducted to compare participant responses to two different social situations. All participants viewed a scene with two children playing cooperatively and a scene with two children arguing while playing. Participants responded to a questionnaire measuring anxiety after viewing each scene to determine if the type of scene viewed had an effect on anxiety scores. The appropriate statistical test to analyze the data in this study is

A) a one-sample t-test.
B) an independent samples t-test.
C) a paired/related samples t-test.
D) an ANOVA.
