In a Reaction That Is First-Order with Respect to Reactant

In a reaction that is first-order with respect to reactant A and second-order with respect to reactant B, the rate of the reaction

A) doubles with a doubling of the concentration of either reactant
B) doubles with a doubling of the concentration of B
C) is halved by a doubling of the concentration of B
D) is tripled by any equal and simultaneous increase in the concentration of A and B
E) quadrupled by a doubling in the concentration of B while the concentration of A is held constant
