The alternative hypothesis should reflect the claim of interest, which is whether there is a difference of more than one credit hour between male and female students in the average number of credit hours taken during a term. Therefore, C is the best choice as it explicitly states the difference being greater than one. A and B do not specify a direction of difference, and D suggests a specific difference being tested (less than one) which is not aligned with the claim of interest.
