Options

A. 4
B. 3
C. 2
D. 5

Answer

To answer the question regarding the classification of tissues into systems based on their topography, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding Tissue Classification**: Tissues in plants can be classified based on their structure and location. This classification helps in understanding the functions and roles of different tissues in plants.

2. **Identifying the Types of Tissue Systems**: There are three main types of tissue systems in flowering plants:
- **Epidermal Tissue System**: This system forms the outer covering of the plant body. It serves as a protective barrier against environmental factors and helps in reducing water loss.
- **Ground Tissue System**: This system constitutes the bulk of the plant body. It is involved in various functions such as photosynthesis, storage, and support.
- **Vascular Tissue System**: This system is responsible for the transportation of water, nutrients, and food throughout the plant. It includes xylem and phloem.

3. **Conclusion**: Based on the classification of tissues into systems, we conclude that there are three types of tissue systems in flowering plants.

### Final Answer:
The correct answer is that there are **3 types of tissue systems** in flowering plants.
