Answer:
The correct answer is - option C.
Explanation:
Using Formula:
Population growth = (birth rate + immigration) – (death rate + emigration)
A) Birth rate = 30
Immigration = 0
Death rate = 30
Emigration = 30
Population growth = (30 +0) – (30 +30)= -60
B) Birth rate = 10
Immigration = 12
Death rate = 0
Emigration = 22
Population growth = (10 + 12) – (0 + 22)=0
C) Birth rate = 6
Immigration = 15
Death rate = 0
Emigration = 9
Population growth = (6 + 15) – (0 + 9)= 12
D) Birth rate = 1
Immigration = 18
Death rate = 20
Emigration = 0
Population growth = (1 + 18) – (20 + 0)= - 1
Scenario (c) would result in positive population growth as other scenarios result in negative or no change.
