(c ) Very young age distribution.
(d) Rapid population growth
( e) Rapidly falling mortality rate
(f) Very old age distribution.

Options

A. (a), (b), (c ), (d)
B. (a), ( c), (d), €
C. (a), (b) (c ), (d)
D. (a), (b), (d), ( e)

Answer

To determine the characteristic demographic features of developing countries, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **High Fertility Rate (Option a)**:
- Developing countries typically have a high fertility rate. This means that women in these countries tend to have more children, contributing to population growth.
- **Conclusion**: This is a characteristic feature of developing countries.

2. **Rapidly Rising Mortality Rate (Option b)**:
- A rapidly rising mortality rate indicates that more people are dying, which would lead to a decrease in population. Developing countries generally work towards reducing mortality rates.
- **Conclusion**: This is NOT a characteristic feature of developing countries.

3. **Very Young Age Distribution (Option c)**:
- Developing countries often have a very young age distribution, meaning a large proportion of the population is made up of children and young adults. This is linked to high fertility rates.
- **Conclusion**: This is a characteristic feature of developing countries.

4. **Rapid Population Growth (Option d)**:
- Rapid population growth is a hallmark of developing countries, driven by high fertility rates and declining mortality rates.
- **Conclusion**: This is a characteristic feature of developing countries.

5. **Rapidly Falling Mortality Rate (Option e)**:
- Developing countries often experience rapidly falling mortality rates due to improvements in healthcare and living conditions, which leads to increased population growth.
- **Conclusion**: This is a characteristic feature of developing countries.

6. **Very Old Age Distribution (Option f)**:
- A very old age distribution would indicate a declining population, as older individuals are more likely to die. This is not typical of developing countries, which usually have a younger population.
- **Conclusion**: This is NOT a characteristic feature of developing countries.

### Final Answer:
The characteristic demographic features of developing countries are:
- (a) High fertility rate
- (c) Very young age distribution
- (d) Rapid population growth
- (e) Rapidly falling mortality rate
