Explanation

To answer the question: "In India, human population has a higher number of younger age group due to," we need to analyze the options provided and understand the demographic trends in India.

### Step-by-Step Solution:

1. **Understanding the Age Structure**:
- India has a significant proportion of its population in the younger age group. This is a characteristic feature of developing countries.

2. **Analyzing the Options**:
- **Option A**: Long lifespan and low birth rate.
- If this were true, there would be a larger elderly population, which contradicts the premise of a higher number of younger individuals. Therefore, this option is incorrect.

- **Option B**: Short lifespan and high birth rate.
- In India, the birth rate is relatively high due to various socio-economic factors, including limited access to education and contraception. Additionally, the lifespan is shorter compared to developed countries, leading to a higher proportion of younger individuals in the population. This option is likely correct.

- **Option C**: Short lifespan and low birth rate.
- A low birth rate would not support a high number of young individuals. Hence, this option is incorrect.

- **Option D**: Birth rate is equal to death rate.
- If the birth rate equaled the death rate, the population would be stable, not skewed towards a younger demographic. Thus, this option is also incorrect.

3. **Conclusion**:
- After analyzing all the options, **Option B (short lifespan and high birth rate)** is the correct answer. This reflects the demographic reality in India, where high birth rates and relatively lower life expectancy contribute to a larger young population.

### Final Answer:
**In India, the human population has a higher number of younger age group due to short lifespan and high birth rate. (Option B)**
