Trimerous condition of floral whorls is present in:

Options

A. angiosperms
B. dicots
C. gymnosperms
D. monocots

Answer

To determine which group of plants exhibits a trimerous condition of floral whorls, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Trimerous Condition**:
- The term "trimerous" refers to floral parts that are arranged in groups of three. This means that each floral whorl (such as sepals, petals, stamens, and carpels) has parts in multiples of three.

2. **Identifying Plant Groups**:
- We need to evaluate the given options:
a. Angiosperms
b. Dicots
c. Gymnosperms
d. Monocots

3. **Analyzing Each Group**:
- **Angiosperms**: This is a broad category that includes both monocots and dicots. Therefore, it is not specific enough to answer the question.
- **Dicots**: Typically, dicots have floral parts in multiples of four or five (tetramerous or pentamerous), not three.
- **Gymnosperms**: These plants do not generally exhibit a trimerous condition in their floral structures.
- **Monocots**: Monocots are characterized by having floral parts in multiples of three. This includes families such as Liliaceae, where the trimerous condition is prominent.

4. **Conclusion**:
- Based on the analysis, the correct answer to the question is **d. Monocots**.

### Final Answer:
The trimerous condition of floral whorls is present in **d. Monocots**.
