The correct answer is an alternative directional hypothesis.

An alternative hypothesis refers to a hypothesis in which a distinction or an influence among the two or more variables is predicted by the researchers, that is, the observed pattern of the data is not because of a chance occurrence.

An alternative directional hypothesis signifies the direction of the tested association, suggesting that one variable is determined to be smaller or larger than the null value, but not both.
