| Birth rate = B | Death Rate = D |
| Emigration = E | Immigration = I |
| Column-I | Column-II |
| A. Population is stable | I. B + I > D + E |
| B. Population is increasing | II. B + I = D + E |
| C. Population is decreasing | III. B + I < D + E |
| IV. B + E > D + I |
(1) A - II, B - I, C – III
(2) A - II, B - IV, C - III
(3) A - III, B - IV, C – I
(4) A - I, B - II, C - IV
