For the reaction $A + B \to \text{products}$,it is found that the rate of the reaction is proportional to the concentration of $A$,but it is independent of the concentration of $B$. Then:
- AThe order of the reaction is $2$ and molecularity is $1$.
- BMolecularity of the reaction is $2$ but order is $1$.
- COrder is $2$ and molecularity is $2$.
- DOrder of the reaction is $2$ but molecularity is $0$.
