Final Answer :
C
Explanation :
A nondirectional research hypothesis states that there is a difference between groups but does not specify the direction of that difference. A null hypothesis states that there is no difference between groups. A directional research hypothesis specifies the direction of the difference, and an error hypothesis is not a commonly used term in hypothesis testing.
