**Core Concept**
The demographic cycle, also known as the population growth cycle, is a model that describes the changes in population growth rates and fertility rates over time. It consists of several stages, each characterized by distinct demographic features.

**Why the Correct Answer is Right**
The correct order of the stages is as follows: Early expanding, Late expanding, High stationary, and Low stationary. The early expanding stage is marked by a rapid increase in population growth rate due to a decline in mortality rates and an increase in fertility rates. As the population grows, the late expanding stage is characterized by an increase in population density, leading to a decline in fertility rates and an increase in mortality rates. The high stationary stage is reached when the population growth rate is stable, with a high population density and low fertility rates. Finally, the low stationary stage is characterized by a low population growth rate, low fertility rates, and a high life expectancy.

**Why Each Wrong Option is Incorrect**
**Option A:** The correct order is not Early expanding, Late expanding, High stationary, and Low stationary; rather, it is Early expanding, Late expanding, High stationary, and Low stationary.
**Option B:** The correct order is not Early expanding, High stationary, Late expanding, and Low stationary; rather, it is Early expanding, Late expanding, High stationary, and Low stationary.
**Option C:** The correct order is not Late expanding, Early expanding, High stationary, and Low stationary; rather, it is Early expanding, Late expanding, High stationary, and Low stationary.
**Option D:** The correct order is not High stationary, Early expanding, Late expanding, and Low stationary; rather, it is Early expanding, Late expanding, High stationary, and Low stationary.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the demographic cycle is a model that helps understand the changes in population growth rates and fertility rates over time. The stages of the demographic cycle can be used to predict and understand the impact of population growth on various aspects of society, including healthcare, education, and economic development.

**Correct Answer:** D. Early expanding, Late expanding, High stationary, and Low stationary.
