Answer

To solve the question regarding the arrangement of unisexual, naked flowers in a cymose manner inside a cup-like involucre of bracts, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Unisexual Flowers**: These are flowers that contain either male (staminate) or female (pistillate) reproductive structures, but not both.
- **Naked Flowers**: This means that the flowers do not have a peduncle (the stalk that supports the flower).
- **Cymose Manner**: This refers to a type of flower arrangement where the main axis of the flower cluster terminates in a flower, and the growth continues with lateral branches, leading to a specific pattern of flowering.
- **Involucre of Bracts**: This indicates that the flowers are surrounded by bracts, which are modified leaves that can support or protect the flower.

2. **Identify the Characteristics**:
- We are looking for a plant that has unisexual, naked flowers.
- The flowers must be arranged in a cymose manner.
- The flowers should be enclosed within a cup-like structure formed by bracts.

3. **Evaluate the Options**:
- **Option 1: Verticillaster of Leucas**: This does not fit the criteria as it has a false whorl and does not exhibit the required characteristics.
- **Option 2: Hypanthodium of Ficus**: This structure is fleshy and does not match the description of unisexual naked flowers arranged in a cymose manner.
- **Option 3: Scyanthium of Euphorbia**: This option fits perfectly as it has unisexual naked flowers arranged in a cymose manner within a cup-like involucre of bracts.
- **Option 4: Compound Umbel of Carrot**: This is a racemose type of inflorescence and does not meet the criteria.

4. **Conclusion**:
- Based on the evaluation, the correct answer is **Scyanthium of Euphorbia**, which exhibits all the specified characteristics.

### Final Answer:
The correct option is **Scyanthium of Euphorbia**.
