$\mathrm{A} \rightarrow$ product (First order reaction). 
Three sets of experiment were performed for a reaction under similar experimental conditions: 
Run $1 \Rightarrow 100 \mathrm{~mL}$ of 10 M solution of reactant A 
Run $2 \Rightarrow 200 \mathrm{~mL}$ of 10 M solution of reactant A
Run $3 \Rightarrow 100 \mathrm{~mL}$ of 10 M solution of reactant $\mathrm{A}+100 \mathrm{~mL}$ of $\mathrm{H}_2 \mathrm{O}$ added. The correct variation of rate of reaction is
