Correct option is A
(A) and (C).
A population pyramid with a broader base indicates a high birth rate and a large number of children. This is because the base of the pyramid represents the youngest age group, and a wider base means that there are more people in this group. A population pyramid with a broader base can also indicate a low death rate, as this would allow the population to grow. However, a low death rate is not always the case, as a high birth rate can also lead to a broader base, even if the death rate is not particularly low.
