The rate of a certain chemical reaction is directly proportional to the square of the concentration of chemical $$A$$ present and inversely proportional to the concentration of chemical $$B$$ present. If the concentration of chemical $$B$$ is increased by $$100$$ percent, which of the following is closest to the percent change in the concentration of chemical $$A$$ required to keep the reaction rate unchanged?

(A) $$100\%$$ decrease.
(B) $$50\%$$ decrease
(C) $$40\%$$ decrease
(D) $$40\%$$ increase
(E) $$50\%$$ increase
