The correct Answer is:
To solve the question regarding the contributions of P. Maheshwari, we will analyze each option provided: 1. **Understanding the Question**: The question asks about the work initiated by P. Maheshwari, an Indian botanist known for his contributions to embryology. 2. **Analyzing Option A - Artificial culture of immature embryos**: - P. Maheshwari did work on the artificial culture of immature embryos. This involves growing embryos in a controlled environment outside the organism, which is a significant aspect of plant embryology. 3. **Analyzing Option B - Test tube fertilization**: - He is also credited with the technique of test tube fertilization. This process involves the fusion of male and female gametes in a test tube, allowing for the study of fertilization and early development stages. 4. **Analyzing Option C - Intra-ovarian pollination**: - P. Maheshwari contributed to the understanding of intra-ovarian pollination, which is the process of pollination occurring within the ovary of the flower. 5. **Analyzing Option D - Physio-chemical approach to study living organisms**: - This option is incorrect. P. Maheshwari was not known for a physio-chemical approach to studying living organisms; his work was primarily focused on embryology and plant reproduction. 6. **Conclusion**: Based on the analysis, options A, B, and C are correct regarding P. Maheshwari's contributions. Therefore, the correct answer is that he initiated work on A (Artificial culture of immature embryos), B (Test tube fertilization), and C (Intra-ovarian pollination). ### Final Answer: P. Maheshwari initiated work on: - A. Artificial culture of immature embryos - B. Test tube fertilization - C. Intra-ovarian pollination
