The table shows the concentrations and pH values for the aqueous solutions of two compounds, $X$ and $Y$. Each compound may be either an acid or a base. Student P decided that $X$ is a strong acid. Student Q decided that the degree of dissociation is smaller in $X(aq)$ than in $Y(aq)$. Which students are right?

- Bneither P nor Q
- CP only
