The null hypothesis is typically a statement that the treatment or factor being tested has no effect. In this case, the null hypothesis would be that alcohol has no effect on short-term memory. Therefore, option B is the correct answer. Option A is the opposite of the alternative hypothesis and option C is a directional hypothesis, which is not appropriate for a null hypothesis. Option D is not relevant to this scenario.
