Answer:
According to the image shown, the country that most closely resembles the population pyramid by age is the United States (option A).
Explanation:
The population pyramid consists of a bar chart that groups the population by age and sex. Each sex is separated into two columns, while from the base to the top the ages are grouped from lowest to highest.
The pyramid by age shown in the image corresponds to a developed country, such as the United States, since the distribution of the population of infants and young people is proportional, being more acute in the advanced ages, acquiring the shape of a bottle.
The "bottle" shape of the population pyramid indicates a controlled birth rate, as well as good availability of basic and sanitary resources, characteristic of a developed country like the United States.
The other options are not correct because:
C and D. In developing countries such as Nigeria and Ethiopia, the birth rate is high - forming a broad base - and the resources available are limited, so there is a progressive decrease as the age groups are distributed, giving a true pyramid shape.
B. Italy, a European country, has a tendency to rhomboidal population pyramids. This is due to a predominance of adult, young and mature, population, low birth rate, good basic and sanitary resources.
