Which is an incorrect statement when discussing molecular collisions leading to the chemical reaction,AB + CD $\rarr$ AD + CB?

A) The faster the motion of the molecules,the more likely they are to collide.
B) The faster the motion of the molecules,the greater the probability that a chemical reaction will occur.
C) The slower the motion of the molecules,the more likely that this reaction will become an equilibrium reaction favoring the left side of the equation.
D) The relationship between molecular collisions and reaction rate is direct.
