For the overall reaction A + 2B ? C
Which of the following mechanisms yields the correct overall chemical equation and is consistent with the rate equation below?
Rate = k[A]×[B]

A)
$\begin{array}{l}\mathrm{A}+\mathrm{B} \rightleftharpoons \mathrm{I} &\text { (fast) } \\\mathrm{I}+\mathrm{A} \rightarrow \mathrm{C} &\text { (slow) }\end{array}$
B)
$\begin{array}{l}\mathrm{A}+\mathrm{B} \rightarrow \mathrm{I} &\text { (slow) } \\\mathrm{I}+\mathrm{B} \rightarrow \mathrm{C} &\text { (fast) }\end{array}$
C)
$\begin{array}{l}2 \mathrm{~B} \rightarrow \mathrm{I} &\text { (slow) } \\\mathrm{A}+\mathrm{I} \rightarrow \mathrm{C} &\text { (fast) }\end{array}$
D)
$\begin{array}{l}2 \mathrm{~B} \rightleftharpoons \mathrm{I}& \text { (fast) } \\\mathrm{I}+\mathrm{A} \rightarrow \mathrm{C} &\text { (slow) }\end{array}$
E)
$\begin{array}{l}\mathrm{A}+2 \mathrm{~B} \rightleftharpoons \mathrm{I} &\text { (fast) } \\\mathrm{I}+\mathrm{B} \rightarrow \mathrm{C}+\mathrm{B} &\text { (slow) }\end{array}$
