Solution
The correct option is B 22
Population growth rate (PGR) is the increase in a country's population during a period of time, usually one year, expressed as a percentage of the population at the start of that period. It reflects the number of births and deaths during a period and the number of people migrating to and from a country.As there are 20 individuals, birth rate is 2 and death rate is 0, also there is no migration. Therefore, 20+2-0=22. Therefore, the correct answer is option B.
