If a reaction has two reactants, and doubling the concentration of one of them doubles the reaction rate, while doubling the concentration of the other leaves the reaction rate unchanged, what is the order of the reaction?
A)0
B)½
C)2
D)1 with respect to the first reactant, and 0 with respect to the second

Question
