C. Stuart Mill
D. Adam Smith

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the concept that relates to the growth of populations and food supply. Specifically, it mentions that populations tend to increase geometrically while food supplies increase arithmetically.

2. **Identifying Key Terms**: The terms "geometrically" and "arithmetically" are crucial. Geometric growth refers to exponential growth, where the population increases rapidly under ideal conditions. In contrast, arithmetic growth refers to a linear increase, which is much slower.

3. **Historical Context**: This concept was introduced in the late 18th century. It is important to identify the key figure associated with this idea.

4. **Identifying the Contributor**: The person who proposed this idea is Thomas Malthus. He discussed these concepts in his work titled "An Essay on the Principle of Population," published in 1798.

5. **Conclusion**: Based on the historical context and the key terms identified, the correct answer to the question is Thomas Malthus.

**Final Answer**: The concept that 'population tends to increase geometrically while food supply increases arithmetically' was put forward by **Thomas Malthus**.
