The Answer would be “B”
Negative Birthrate;
At the extreme, other countries are experiencing negative population growth. Again, this means more deaths and emigration, or the leaving of a country, than births and immigration, or entering of a country
In answer “B” It’s clearly explaining that the death/birth ratio is high which means;
Death > Birth
This then concludes the statement that it is an example of negative population growth since there’s more people dying then coming into this world.
