One-tailed Test
A statistical test that determines the direction of a relationship between variables, assessing whether one mean is greater than or less than another.
Two-tailed Test
A statistical test that considers both directions of an effect or relationship, testing for the possibility of positive or negative differences.

Final Answer :
A
Explanation :
A one-tailed test is appropriate when we have a directional hypothesis, in which we predict the relationship between two variables to be either positive or negative. A one-tailed test allows us to focus on one specific direction of the relationship and increases our power to detect a significant effect in that direction. ANOVA and Cohen's d are not appropriate for testing the directionality of a relationship. A two-tailed test is used for nondirectional hypotheses.
