The correct Answer is:

### Step-by-Step Solution: 1. **Understanding the Age Pyramid**: An age pyramid, also known as a population pyramid, visually represents the distribution of various age groups in a population. It typically has age categories on the vertical axis and the population size on the horizontal axis. 2. **Identifying the Base of the Pyramid**: The base of the pyramid represents the youngest age group, which includes children and infants. A broad base indicates a large number of individuals in this age group. 3. **Interpreting a Broad Base**: When the base of the pyramid is broad, it signifies that there is a high percentage of young individuals in the population. This suggests a high birth rate and a growing population. 4. **Analyzing Other Age Groups**: The middle section of the pyramid represents the reproductive age group, while the top section represents the older population. In a pyramid with a broad base, the proportion of older individuals is typically lower compared to the younger individuals. 5. **Conclusion**: Therefore, an age pyramid with a broad base indicates a high percentage of young individuals in the population. ### Final Answer: The age of a pyramid with a broad base indicates a **high percentage of young individuals**. ---

Study the age pyramids given below and select the correct statements regarding these.

`A` is a triangular age pyramid, where prereproductive stage is very large as compared to the reproductive and post-reproductive stages of the population. This type of age sturcture indicates that the population. This type of ae sturcture indicates that the population would increase rapidly.

`B` is an inverted bell shaped age pyramid, where number of pre-reproductive and reproductive individuals is almost equal. This type of age structure indicates that the population is stable.

`C` is an urn shaped age pyramid, where more number of reproductive individuals are present. This type of age structure indicates that the population is declining.
