B. Flower colour in Antirrhinum majus
C. Flower colour in the evening primrose
D. More than one option is correct

Answer

To solve the question regarding where incomplete dominance is found, we will analyze the options provided and understand the concept of incomplete dominance.

### Step-by-Step Solution:

1. **Understanding Incomplete Dominance**:
- Incomplete dominance occurs when the heterozygous phenotype is a blend of the two homozygous phenotypes. This means that neither allele is completely dominant over the other, resulting in a third phenotype that is a mix of the two.

2. **Analyzing the Options**:
- **Option A: Starch grain size in P**:
- This trait does not exhibit incomplete dominance; it is an example of codominance. Therefore, this option is incorrect.

- **Option B: Flower color in Androgena midges**:
- There is no widely recognized evidence that this trait exhibits incomplete dominance. Thus, this option is also likely incorrect.

- **Option C: Flower color in Evening Primrose**:
- The evening primrose (Oenothera) is a classic example of incomplete dominance. When red and white flowers are crossed, the resulting offspring have pink flowers, demonstrating a blend of the two colors. This option is correct.

- **Option D: More than one option is correct**:
- Since only option C is correct, this option cannot be true.

3. **Conclusion**:
- Based on the analysis, the correct answer is **Option C: Flower color in Evening Primrose**.

### Final Answer:
**C. Flower color in Evening Primrose**
