In countries that are in stage 2 of the demographic transition, an increase in doubling time would be most likely to occur as a direct result of **decreased CDR** (Crude Death Rate).
As countries transition from high birth and death rates to lower death rates (due to improvements in health, sanitation, etc.), the population grows rapidly, leading to a shorter doubling time. In stage 2, the decrease in CDR typically causes a population explosion, and if CDR decreases further, the doubling time may decrease even more compared to before.
Thus, an increase in doubling time is less likely to be influenced by CDR decreasing, it's more reasonable to say that population growth is triggered and stays low when the death rate falls but birth rates remain high. Therefore, decreased CDR is the best option related to the effects observed during this stage.
