C. I, IIl, IV
D. III, IV, V

Answer

To determine the causes of higher population growth based on the given statements, let's analyze each statement step by step:

### Step-by-Step Solution:

1. **Rapid Decline in Death Rate**:
- A rapid decline in the death rate means that fewer people are dying in a given population. This leads to an increase in the overall population because more individuals are surviving.
- **Conclusion**: This statement is a cause of higher population growth.

2. **Rapid Increase in MMR and IMR**:
- MMR (Maternal Mortality Rate) refers to the number of maternal deaths per 100,000 live births, and IMR (Infant Mortality Rate) refers to the number of infant deaths per 1,000 live births. An increase in either of these rates indicates higher mortality among mothers and infants, which would lead to a decrease in population growth.
- **Conclusion**: This statement does not contribute to higher population growth.

3. **Rapid Decline in MMR and IMR**:
- A rapid decline in MMR and IMR indicates that fewer mothers and infants are dying. This would lead to an increase in population growth as more individuals survive through childbirth.
- **Conclusion**: This statement is a cause of higher population growth.

4. **Increase in Number of People in the Reproductive Age Group**:
- An increase in the number of individuals in the reproductive age group means there are more people capable of having children. This can lead to an increase in birth rates, contributing to higher population growth.
- **Conclusion**: This statement is a cause of higher population growth.

5. **Rapid Increase in Death Rate**:
- A rapid increase in the death rate means that more individuals are dying, which would lead to a decrease in population growth.
- **Conclusion**: This statement does not contribute to higher population growth.

### Summary of Causes of Higher Population Growth:
Based on the analysis:
- **Causes of higher population growth**:
- Rapid decline in death rate (Statement I)
- Rapid decline in MMR and IMR (Statement III)
- Increase in number of people in the reproductive age group (Statement IV)

Thus, the correct statements that contribute to higher population growth are **I, III, and IV**.
