Three different metals are each reacted separately with dilute hydrochloric acid and with water. The outcomes are shown. What is the reactivity order of the metals, beginning with the most reactive?
- AR $\rightarrow$ S $\rightarrow$ T
- BS $\rightarrow$ R $\rightarrow$ T
- CT $\rightarrow$ R $\rightarrow$ S
- DT $\rightarrow$ S $\rightarrow$ R
