The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Avena Curvature Test**: The Avena curvature test is a bioassay used to determine the biological activity of hormones, specifically auxins, by measuring their effect on plant parts. 2. **Identifying the Scientists**: The question lists several scientists: J.C. Boss, F.W. Wendt, Thiemann, and Coog. We need to identify who first conducted the Avena curvature test. 3. **Analyzing the Contributions**: - **J.C. Boss**: Known for proving that plants have life and inventing the Crescograph, which measures plant reactions. - **F.W. Wendt**: Conducted the Avena curvature test specifically for indole acetic acid. - **Thiemann**: Proposed the concept of phytochromes. - **Coog**: Associated with the discovery of cytokinins. 4. **Conclusion**: The Avena curvature test was first conducted by F.W. Wendt, making him the correct answer to the question. 5. **Final Answer**: The Avena curvature test was first of all done by **F.W. Wendt**. ---
