Most advanced amongst the dicots is

Options

A. Asteraceae
B. Malvaceae
C. Brassicaceae
D. Fabaceae.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which family is considered the most advanced among the dicots. Dicots are a group of flowering plants that have two cotyledons.

2. **Identifying the Options**: The options provided are:
- Asteraceae
- Malvaceae
- Brassicaceae
- Fabaceae

3. **Defining Dicots**: Dicots, or dicotyledons, are characterized by having two seed leaves (cotyledons). They are part of the angiosperms, which are flowering plants.

4. **Analyzing the Families**:
- **Asteraceae**: This family includes plants like daisies and sunflowers. They are primarily herbs and shrubs, which typically have a short life cycle, allowing for rapid reproduction and a high number of progeny.
- **Malvaceae**: This family includes plants like hibiscus and cotton. While they are important, they do not have the same level of advanced characteristics as Asteraceae.
- **Brassicaceae**: This family includes plants like mustard and cabbage. They are also significant but are not considered the most advanced.
- **Fabaceae**: This family includes legumes like beans and peas. They are important for nitrogen fixation but do not match the advanced characteristics of Asteraceae.

5. **Reasons for Asteraceae Being Advanced**:
- **Life Cycle**: Members of the Asteraceae family have a short life cycle, leading to more generations and thus more plants.
- **Seed Dispersal**: They possess an organ called Pappus, which aids in wind dispersal of seeds, allowing them to spread over greater distances.
- **Simple Flower Structure**: Their simple flowering type and inflorescence contribute to their ability to produce more plants.

6. **Conclusion**: Based on the analysis, Asteraceae is considered the most advanced family among the dicots due to its reproductive efficiency, advanced seed dispersal mechanisms, and simple floral structures.

### Final Answer:
The most advanced amongst the dicots is **Asteraceae**.
