Consider the equation \(3 \mathrm{~A}+\mathrm{B} ightarrow \mathrm{C}+\mathrm{D}\). You react 4 moles of A with 2 moles of \(\mathrm{B}\). Which of the following is true?

a. The limiting reactant is the one with the higher molar mass.

b. A is the limiting reactant because you need 6 moles of \(\mathrm{A}\) and have 4 moles.

c. B is the limiting reactant because you have fewer moles of \(\mathrm{B}\) than \(\mathrm{A}\).

d. B is the limiting reactant because three A molecules react with each \(B\) molecule.

e. Neither reactant is limiting.

Justify your choice. For those you did not choose, explain why they are incorrect.
