$(A)$ The stronger the temperature dependence of the rate constant, the higher is the activation energy.
$(B)$ If a reaction has zero activation energy, its rate is independent of temperature.
$(C)$ The stronger the temperature dependence of the rate constant, the smaller is the activation energy.
$(D)$ If there is no correlation between the temperature and the rate constant then it means that the reaction has negative activation energy.
