The answer is "c", because if the temperature of a reactant increases, its average molecular kinetic energy of a molecule will increase and leads to increase the number of collisions between reactants.

Both increase in the number of effective collisions and increases in the average kinetic energy is attributable to increase in temperature.

The option given is true for the catalyst as a catalyst reduce activation energy no doubt that temperature increases kinetic energy but reaction takes by the number of effective collisions (which is a fraction) implies that total KE is not utalised.
According to me, option A is correct.
According to me, option A is correct.

Yes. The answer is c because if the temperature increases that the average kinetic energy of a molecule also increased so that the collision also increase but the only fraction of molecule collides effectively.

It must be C because increase in temperature increases kinetic energy of molecules which in turn cause increase no of collisions.

Activation energy decreases in the presence of catalyst but not by increasing the temperature.
Increasing the temperature increases the no of collisions.
Increasing the temperature increases the no of collisions.
