Identifying Null and Alternative Hypotheses in Hypothesis Testing

In a recent study concerning the impact of a new medication on blood pressure levels, a researcher sets up a hypothesis test to determine if the medication has a significant effect. The null hypothesis ( extit{H0}) states that the medication does not change blood pressure levels, while the alternative hypothesis ( extit{H1}) holds that the medication does have a significant effect on blood pressure. Which of the following correctly identifies both the null and alternative hypotheses?
