The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Kingdom:** The question refers to the Kingdom Plantae, which includes various divisions of plants. 2. **Focus on Gymnosperms:** Gymnosperms are a significant division within the Kingdom Plantae. They are characterized by having seeds that are not enclosed in an ovary (unlike angiosperms). 3. **Determine the Origin Timeframe:** The question states that gymnosperms originated approximately 265 million years ago. This timeframe is crucial for identifying the correct geological era. 4. **Relate to Dinosaurs:** The question mentions that gymnosperms flourished during the time when dinosaurs were predominant. This suggests we need to find an era that corresponds to both gymnosperms and dinosaurs. 5. **Identify the Correct Era:** The Mesozoic Era is known as the "Age of Reptiles" and is divided into three periods: Triassic, Jurassic, and Cretaceous. Dinosaurs were particularly abundant during the Jurassic Period, which is part of the Mesozoic Era. 6. **Conclusion:** Therefore, the era in which gymnosperms flourished and dinosaurs were predominant is the Mesozoic Era. **Final Answer:** Mesozoic Era ---
