**Step-by-Step Solution:**

2. **Floral Rewards**: Plants provide rewards to attract pollinators. These rewards can be in various forms, but the most common ones are nectar and pollen.

3. **Identifying Options**:
- **Option 1**: Nectar and pollen - This is a common reward as nectar serves as food for pollinators, and pollen can also be consumed.
- **Option 2**: Pollen and enzymes - While pollen is provided, enzymes are not a typical floral reward.
- **Option 3**: Hormones and nectar - Nectar is provided, but hormones are not a floral reward.
- **Option 4**: All of these - This option is incorrect as not all listed items are provided as rewards.

4. **Conclusion**: The most accurate answer is Option 1, which states that the common floral rewards provided by plants to pollinators are nectar and pollen.

**Final Answer**: Option 1: Nectar and pollen.
