Logistic growth in a population is characterized by:
| 1. | A constant rate of growth regardless of population size. |
| 2. | An exponential growth followed by a stabilization at the carrying capacity. |
| 3. | Decrease in population size after reaching the carrying capacity. |
| 4. | A linear increase in population size over time. |

Consider the given two statements:
| Assertion (A): | A population experiencing high natality rates will always exhibit exponential growth. |
| Reason (R): | Exponential growth occurs only when resources are unlimited. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A). |
| 2. | Both (A) and (R) are True but (R) does not explain (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
