Final Answer :
A
Explanation :
When the research hypothesis predicts the direction of a relationship, the test is one-tailed. This is because the hypothesis is only looking for an effect in one direction, rather than both directions (which would be a two-tailed test). The terms "direct" and "positive" do not necessarily refer to whether the hypothesis predicts a specific direction, so they are not the best choices for this question.
