Angiospermic plants are charcterised by the presence of
I. Double fertilisation
II. Tripolid endosperm
III. Diploid endosperm
Choose the correct option with correct statements

Options

A. I and II
B. I and III
C. II and III
D. All of these

Answer

### Step-by-Step Solution:

1. **Understanding Angiospermic Plants**:
- Angiospermic plants, also known as flowering plants, are characterized by certain unique reproductive features.

2. **Identifying Double Fertilization**:
- One of the key characteristics of angiospermic plants is double fertilization. This process involves the fusion of one male gamete with the egg cell to form a zygote, and the fusion of another male gamete with two polar nuclei to form the endosperm.

3. **Examining the Endosperm**:
- The endosperm in angiospermic plants is triploid (3n), which means it has three sets of chromosomes. This is formed as a result of the fusion of one male gamete with the two polar nuclei in the central cell of the embryo sac.

4. **Clarifying the Statements**:
- Statement I: Double fertilization - **True** (This is a defining characteristic of angiosperms).
- Statement II: Triploid endosperm - **True** (The endosperm is indeed triploid).
- Statement III: Diploid endosperm - **False** (The endosperm is not diploid; it is triploid).

5. **Conclusion**:
- Based on the analysis, the correct statements regarding angiospermic plants are I and II. Therefore, the correct option includes the statements about double fertilization and triploid endosperm.

### Final Answer:
The correct option includes statements I and II:
- I. Double fertilization (True)
- II. Triploid endosperm (True)
- III. Diploid endosperm (False)
