Populations explosion in India is due to:

Options

A. Decreased mortality
B. Illiteracy
C. Increased natality
D. All of the above

Answer

To solve the question regarding the causes of population explosion in India, we need to analyze each of the given options:

1. **Decreased Mortality**: This refers to a reduction in the death rate. When fewer people die, the population grows. Improved healthcare, nutrition, and sanitation contribute to decreased mortality rates, leading to population growth.

2. **Illiteracy**: Illiteracy can lead to a lack of awareness about family planning and contraceptive methods. Many individuals may not have access to education about reproductive health, resulting in higher birth rates and contributing to population explosion.

3. **Increased Natality**: This means an increase in the birth rate. If more babies are born than the number of people dying, the population will grow. High birth rates are often seen in regions where there is limited access to family planning.

4. **All of the Above**: This option suggests that all the previously mentioned factors contribute to the population explosion.

Now, let's summarize the analysis:

- Decreased mortality contributes to population growth by reducing the number of deaths.
- Illiteracy affects knowledge about family planning, leading to higher birth rates.
- Increased natality directly increases the population size.

Given that all three factors (decreased mortality, illiteracy, and increased natality) play a significant role in the population explosion in India, the correct answer is:

**Answer: All of the above.**
