Explanation:

• Option 1: If emigration rate > death rate, population would likely decrease as more are leaving (emigrating) than dying.
• Option 2: Death rate > immigration: Death reduces population, and if immigration (in - flow) is less than death rate, population would decrease.
• Option 3: Birth rate < death rate: Births add to population, deaths subtract. If births < deaths, population would decrease.
• Option 4: Immigration > emigration: Immigration is in - flow, emigration is out - flow. When in - flow > out - flow, it contributes to an increase in population.

Answer:

The immigration of the population is greater than the emigration.
