Answer

**Step-by-Step Text Solution:**

1. **Understanding the Rivet Popper Hypothesis**: The Rivet Popper Hypothesis is a concept in ecology that explains the importance of biodiversity in maintaining the stability and functionality of ecosystems. It suggests that each species in an ecosystem can be thought of as a rivet in an airplane.

2. **Identifying the Originator**: The hypothesis was proposed by Paul Ehrlich, an ecologist known for his work in biodiversity and conservation.

3. **Explanation of the Hypothesis**: According to the hypothesis, the loss of a single species (or rivet) may not have a significant impact on the ecosystem. However, as more species are lost, the stability and functionality of the ecosystem begin to deteriorate, much like an airplane losing rivets that are crucial for its structure.

4. **Conclusion**: Based on the information provided, the correct answer to the question "Rivet popper hypothesis was given by" is (a) Paul Ehrlich.

**Final Answer**: (a) Paul Ehrlich
