Vedclass · Answer

(D) The correct answer is $D$. $1$. An age-sex pyramid with a broad base indicates a rapidly growing population,as it shows a high proportion of individuals in the pre-reproductive age group ($0-9$ years). $2$. Comparing the two pyramids,pyramid $B$ has a wider base compared to pyramid $A$. This indicates that pyramid $B$ represents the population twenty years ago (the earlier state) when the growth rate was higher. $3$. Pyramid $A$ has a relatively narrower base compared to $B$,indicating a reduction in the proportion of the youngest age group. This reflects the impact of measures taken to reduce population growth over the twenty-year period. $4$. Therefore,$A$ is the more recent pyramid,and it shows a slight reduction in the growth rate compared to $B$.
