The correct Answer is:
To solve the assertion-reason question, we will analyze both the assertion and the reason step by step. ### Step 1: Analyze the Assertion - **Assertion**: "The rate at which a population can be expected to grow in the future can be assessed graphically by means of a population pyramid." - **Explanation**: This statement is true. A population pyramid, also known as an age pyramid, visually represents the distribution of various age groups in a population. By examining the proportions of pre-reproductive, reproductive, and post-reproductive age groups, one can predict future population growth. A larger base (pre-reproductive) suggests a potential increase in population, while a smaller base indicates stability or decline. ### Step 2: Analyze the Reason - **Reason**: "A triangular population pyramid is characteristic of a country whose population is stable, neither growing nor shrinking." - **Explanation**: This statement is false. A triangular population pyramid indicates a high number of young individuals (pre-reproductive age), which suggests that the population is likely to grow rapidly in the future as these individuals enter the reproductive age group. A stable population is typically represented by a bell-shaped pyramid, where the reproductive age group is the largest, indicating balance among age groups. ### Step 3: Conclusion - Since the assertion is true and the reason is false, the correct answer is that the assertion is true, but the reason is false. ### Final Answer: - **Assertion is true, Reason is false.** (Option C) ---
