The stages of demographic transition are a way to understand the changes in population growth rates over time.

Option 1: High death rate and birthrate, low growth rate. This describes the first stage of demographic transition, where both the death rate and birthrate are high, resulting in a low growth rate.

Option 2: Rapid decline in death rate, continued low birthrate, very low growth rate. This describes the second stage of demographic transition. In this stage, the death rate starts to decline rapidly, but the birthrate remains low, leading to a very low growth rate.

Option 3: Rapid decline in birthrate, continued decline in death rate. This describes the third stage of demographic transition. In this stage, the birthrate starts to decline rapidly, while the death rate continues to decline as well.

Option 4: Low death rate and birthrate, low growth rate. This describes the fourth stage of demographic transition. Both the death rate and birthrate are low, resulting in a low growth rate.

The correct answer is Option 4, as it includes both the first and fourth stages of demographic transition.
