Hint:

Answer 1

The Correct Option is D

Concept:
Population size changes due to birth, death, immigration and emigration.

Step 1: Match Natality.
Natality means birth rate. \[ A\rightarrow III \]

Step 2: Match Mortality.
Mortality means death rate. \[ B\rightarrow IV \]

Step 3: Match Immigration.
Immigration adds individuals of the same species into a population. \[ C\rightarrow I \]

Step 4: Match Emigration.
Emigration means individuals move out from the population. \[ D\rightarrow II \] Therefore: \[ A-III,\ B-IV,\ C-I,\ D-II \] \[ \therefore \text{Correct Answer is (D)} \]
