Final Answer :
B
Explanation :
If a research hypothesis does not predict the direction of a relationship, the test should be two-tailed. A two-tailed test allows for the possibility of a positive or negative relationship between the variables being tested. In contrast, a one-tailed test only allows for the possibility of a positive or negative relationship in a specific direction. Direct and positive are not relevant to the type of test being conducted.
