Sign test for a median

Let $X_1, X_2, \dots, X_5$ be random observations from a continuous distribution. Let $\theta_p$ be the $p$-th population quantile. Consider the following hypotheses $H_0: \theta_{1/2} = 2.5$ against $H_1: \theta_{1/2} > 2.5$. Let $X_{(r)}$ denote the $r$-th order statistic of the given observations. Then which of the following is a critical region of a level 0.05 test?
