Hmm, I'm not sure about this one. The question mentions 'class score distribution', so doesn't that imply the data is normally distributed? I'd go with B, just to be safe.

Option C seems like the obvious choice here. The F-test is designed to compare variances, so if the test is significant, the variances must be different. Easy peasy!
