Options

A. all flowers are covered by a sheath
B. all flowers are brought more or less to the same level
C. all flower arise from a common point
D. none of the above.

Answer

### Step-by-Step Solution:

1. **Understanding Corymb Inflorescence**: Corymb is a type of racemose inflorescence where the flowers are arranged in such a way that they appear to be at the same level. This is achieved through the varying lengths of the pedicels (the stalks that support individual flowers).

2. **Analyzing the Options**:
- **Option 1**: "All flowers are covered by sheet." - This statement does not accurately describe corymb inflorescence.
- **Option 2**: "All flowers are brought more or less to the same level." - This statement correctly describes the arrangement of flowers in corymb inflorescence.
- **Option 3**: "All flowers arise from a common point." - While flowers do arise from a common point, this description is more characteristic of a simple raceme rather than specifically highlighting the level arrangement seen in corymb.
- **Option 4**: "None of the above." - This option is incorrect since option 2 is valid.

3. **Conclusion**: Based on the analysis, the correct answer is **Option 2**, which states that "all flowers are brought more or less to the same level."
