If in a certain country, the number of births this year greatly surpassed the number of births last year, the number of deaths this year was the same as last year, and there was no migration to or from other countries, the population growth rate would rise. Option A is correct.
Since the number of deaths remains the same that the previous year and there was no people coming or living the country, population should grow since the birth rate increases and there are not more deaths than before.
