C. Lemon , (a) Stamens are polyadelphous (b) Placenta is axial and the ovules are attached to it in a multilocular ovary
D. Castor : (a) The seed has one cotyledon (b) The seed has endosperm

Answer

To solve the question regarding the plant and its properties, we will analyze each option provided and determine which statement is incorrect.

### Step-by-Step Solution:

1. **Identify the Plant and Properties**: The question presents a plant and two properties associated with it. We need to evaluate each option to find the incorrect statement.

2. **Evaluate Option A - Cucumber**:
- **Property 1**: "Stem tendrils are formed from axillary buds."
- This statement is **correct**. In cucumbers, the axillary buds do indeed modify into tendrils for support.
- **Property 2**: "The margin of the phyllum is growing upward and closing the ovary part of the flower rises above the ovary."
- This statement is also **correct**. This describes the epigynous condition found in cucumbers where the ovary is inferior.

3. **Evaluate Option B - Rose**:
- **Property 1**: "The ovary is half inferior."
- This statement is **correct**. Roses have a half-inferior ovary, which is characteristic of a perigynous flower.
- **Property 2**: "Its gynoecium is polycarpillary and apocarpous."
- This statement is also **correct**. In roses, the carpels are free, confirming the apocarpous condition.

4. **Evaluate Option C - Lemon**:
- **Property 1**: "The stamens are polyadelphous."
- This statement is **correct**. Lemons have stamens that are grouped into two or more bundles (polyadelphous).
- **Property 2**: "The placenta is axial and the ovules are attached to it in a multilocular ovary."
- This statement is also **correct**. Lemons exhibit axial placentation with a multilocular ovary.

5. **Evaluate Option D - Castor**:
- **Property 1**: "The seed has only one cotyledon."
- This statement is **incorrect**. Castor seeds are dicotyledonous, meaning they have two cotyledons.
- **Property 2**: Not provided, but since the first property is incorrect, we can conclude that option D is the one we are looking for.

### Conclusion:
The incorrect statement is found in **Option D** regarding castor, where it incorrectly states that the seed has only one cotyledon.

### Final Answer:
**Option D is incorrect.**
