Calcium reacts with cold water to release hydrogen. When lead is heated in air, it reacts slowly to make an oxide, but it shows almost no reaction with steam. Silver does not react with air or with water. Zinc reacts with steam when heated to produce hydrogen. What is the order of reactivity starting with the least reactive?
- Acalcium $\rightarrow$ lead $\rightarrow$ zinc $\rightarrow$ silver
- Bcalcium $\rightarrow$ zinc $\rightarrow$ lead $\rightarrow$ silver
- Csilver $\rightarrow$ lead $\rightarrow$ zinc $\rightarrow$ calcium
- Dsilver $\rightarrow$ zinc $\rightarrow$ lead $\rightarrow$ calcium
