The number of individuals in the reproductive age group is more than the number of individuals in the pre-reproductive age group, the shape of its age pyramid would reflect the growth status of the population as:

The correct option is Expanding.

An age pyramid is a graphical representation that shows the distribution of various age groups in a population. A population is typically analyzed by dividing it into three ecological age groups:
1. Pre-reproductive group: Consists of young individuals who have not yet reached reproductive maturity.
2. Reproductive group: Consists of individuals who are actively reproducing.
3. Post-reproductive group: Consists of older individuals who are past the age of reproduction.

When the number of individuals in the reproductive age group is more than those in the pre-reproductive age group, the population contains a high concentration of individuals who are currently contributing to the birth rate. Since a large portion of the population is actively producing offspring, the total number of births will be high, leading to a significant addition of new individuals to the population. This high birth rate drives a rapid increase in the population size, reflecting an expanding growth status.
