Answer: Option B
Explanation:
Positive population growth means that there is increased birth and there is no deaths in the country. To bring it to zero population growth (ZPG) there has to be no growth or decline in the population growth.
Economy is supposed to be in a steady state when there is zero population growth. Total output growth will become lower with ZPG and the growth of the output per person will remain the same as before as there is no increase in population.
