Select the incorrect statement.

Options

A. Apomixis is observed in grasses.
B. Mango is one seeded fruit.
C. Hard seed coat is meant for protection.
D. Most of the fruits are parthenocarpic fruits.

Answer

To solve the question of selecting the incorrect statement, we will analyze each provided option step by step.

### Step-by-Step Solution:

1. **Examine the First Statement:**
- **Statement:** Apomixis is observed in classes.
- **Analysis:** Apomixis is indeed a form of asexual reproduction that occurs without fertilization and does not involve meiosis. This statement is correct.

2. **Examine the Second Statement:**
- **Statement:** Mango is a one-seeded fruit.
- **Analysis:** This statement is misleading. While mangoes typically have a single large seed, they are classified as drupe fruits, which can contain more than one seed in some varieties. Therefore, this statement is incorrect.

3. **Examine the Third Statement:**
- **Statement:** Hard seed coat is meant for protection.
- **Analysis:** This statement is correct. The hard seed coat does serve to protect the internal parts of the seed from environmental factors, including drying out and entry of insects.

4. **Examine the Fourth Statement:**
- **Statement:** Most of the fruits are parthenocarpic fruits.
- **Analysis:** This statement is incorrect. While parthenocarpy (development of fruit without fertilization) does occur, it is not true that most fruits are parthenocarpic. Many fruits develop through fertilization and contain seeds.

### Conclusion:
Based on the analysis, the incorrect statements are the second and fourth options. However, since the question asks for a single incorrect statement, the most misleading one is the second statement: "Mango is a one-seeded fruit."

### Final Answer:
The incorrect statement is: **Mango is a one-seeded fruit.**
