The ionic equations below show how four metals, P, Q, R and S, react with solutions containing salts of those same metals. $\text{P} + \text{Q}^{2+} \rightarrow$ no reaction $\text{R} + \text{P}^{2+} \rightarrow \text{R}^{2+} + \text{P}$ $\text{Q} + \text{S}^{2+} \rightarrow \text{Q}^{2+} + \text{S}$ $\text{S} + \text{P}^{2+} \rightarrow \text{S}^{2+} + \text{P}$ $\text{S} + \text{R}^{2+} \rightarrow \text{S}^{2+} + \text{R}$ $\text{S} + \text{Q}^{2+} \rightarrow$ no reaction Which is the correct reactivity order for the metals?
- AP, R, S, Q
- BQ, R, S, P
- CQ, S, R, P
- DS, Q, P, R
