A. 1
B. 2
C. 3
D. 4

Answer

To determine how many statements are incorrect, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement (i)**: "The function of germ pore is initiation of the pollen tube."
- **Analysis**: The germ pore is indeed the area on the pollen grain where the pollen tube emerges. Therefore, this statement is **correct**.

2. **Statement (ii)**: "The coconut water and edible part of coconut are equivalent to endosperm and endocarp, respectively."
- **Analysis**: The coconut water is the liquid endosperm, while the edible part of the coconut is the fleshy endosperm. The endocarp is the hard shell surrounding the seed. Thus, this statement is **incorrect**.

3. **Statement (iii)**: "When pollen is shed at the three-celled stage, syngamy occurs more quickly than the pollen when shed at the two-celled stage."
- **Analysis**: Pollen grains are typically shed at the two-celled stage, and they develop into the three-celled stage after landing on the stigma. Therefore, this statement is **incorrect**.

4. **Statement (iv)**: "Intine is made up of cellulose and pectin."
- **Analysis**: Intine, which is the inner layer of the pollen grain wall, is indeed composed of cellulose and pectin. Thus, this statement is **correct**.

5. **Statement (v)**: "Pollen grains in some plants remain viable for months."
- **Analysis**: This is true as some species of pollen can remain viable for extended periods, sometimes even months. Therefore, this statement is **correct**.

### Summary of Statements:
- Correct Statements: (i), (iv), (v)
- Incorrect Statements: (ii), (iii)

### Conclusion:
There are **2 incorrect statements**.

### Final Answer:
**2**
