Final Answer :
A
Explanation :
A one-tailed test is used to test a directional research hypothesis, where the hypothesis states that a particular relationship or effect will occur in a specific direction. In contrast, a two-tailed test is used for a non-directional hypothesis, where the hypothesis states that there will be a difference or relationship, but not in a specific direction. Nonparametric and frequency tests are not relevant to testing directional hypotheses.
