To determine which option is not a monocot, we need to understand the definitions and characteristics of monocots and dicots.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Monocots**: These are plants that have only one cotyledon (the first leaf that appears from a seed). Examples include grasses, lilies, and orchids.
- **Dicots**: These are plants that have two cotyledons. Examples include roses, sunflowers, and beans.

2. **Examine the Options**:
- **Option A: Rose** - This is a dicot because it has two cotyledons.
- **Option B: Palm** - This is a monocot as it has one cotyledon.
- **Option C: Orchid** - This is also a monocot.
- **Option D: Banana** - This is a monocot as well.

3. **Identify the Non-Monocot**:
- Since the question asks for which option is not a monocot, we can see that the rose (Option A) is the only plant listed that is a dicot.

4. **Conclusion**:
- The answer to the question "Which is not a monocot?" is **Option A: Rose**.
