Answer 1

The correct option is B

1 and 3 only

Explanation:

Statement 1 is correct: The age-sex pyramid of a triangular shape with a wide base is typical of less developed countries. These have larger populations in lower age groups due to high birth rates.


Statement 2 is incorrect: When birth and death rate are equal then a constant population scenario occurs (considering migration as zero).

Narrow base and tapered top occurs when population growth is negative. Example - Japan


Statement 3 is correct: Constant population: Australia’s age-sex pyramid is bell shaped and tapered towards the top. This shows birth and death rates are almost equal leading to a near constant population.
