The Kinetics of a Reaction Is Studied at 25 $\degree$ C and at 50

The kinetics of a reaction is studied at 25 $\degree$ C and at 50 $\degree$ C.Which of the following statements is correct?

A) The rate of the reaction at 50 $\degree$ C will be lower than the rate at 25 $\degree$ C, since the molecules will be moving too fast to collide effectively.
B) The rate of the reaction at 50 $\degree$ C will be twice that of the rate at 25 $\degree$ C, since the temperature has doubled.
C) The rate of the reaction at 50 $\degree$ C will be greater than the rate at 25 $\degree$ C, since the activation energy will be lower at the higher temperature.
D) The rate of the reaction at 50 $\degree$ C will be greater than the rate at 25 $\degree$ C, since a greater fraction of the molecules will possess sufficient energy to react at the higher temperature.
E) None of these statements is correct.
