Solution

The correct option is B increasing the temperature
The rate constant of a chemical reaction can be increased by Increasing the temperature.
The temperature dependence of rate constant is given by the Arrhenius equation.

$k = A e^{(- E a / R T)}$
With an increase in temperature, $E_{a} / R T$ decreases and $e x p (- E_{a} / R T)$ increases. This increases the rate and rate constant.
