Solution

The correct option is B decrease
A population having more old individuals than young individuals tend to decrease after some years. This is because these individuals have already completed their reproductive age and their contribution towards adding new individuals in the population is very less compared to a population with more individuals in the reproductive and the pre-reproductive age groups.
