Who gave principle that man tends to multiply by geometrical progression then food supply?

Options

A. Malthus
B. Darwin
C. Haldon
D. Gandhi

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the principle that states humans tend to multiply in a geometric progression when food supply is sufficient.

2. **Identifying the Principle**: The principle in question relates to population growth in relation to food supply. It suggests that if food is abundant, human populations can grow rapidly.

3. **Geometric Progression Explained**: In mathematical terms, geometric progression means that if there are 'x' individuals in one generation, the next generation can potentially be 'x²' (x squared), and the following generation could be 'x³' (x cubed), and so on, depending on the availability of resources.

4. **Historical Context**: This principle was articulated by Thomas Robert Malthus, an economist and demographer, in his work on population dynamics.

5. **Evaluating Options**: The options provided include:
- Malthus
- Darwin
- Hardin
- Gandhi

6. **Selecting the Correct Answer**: Among the options, Malthus is the correct answer as he is the one who proposed the principle regarding population growth in relation to food supply.

7. **Final Answer**: Therefore, the correct answer to the question is Malthus.
