Which of the following is a pre-fertilization event in flowering plants ?

Options

A. Transfer of pollen
B. Formation of fruit
C. Formation of seeds
D. Growth of plant

Answer

### Step-by-Step Solution:

1. **Understanding Pre-Fertilization Events**:
- Pre-fertilization events are those that occur before the fusion of male and female gametes in flowering plants. These events are crucial for sexual reproduction.

2. **Identifying the Options**:
- The options provided are:
- A) Transfer of pollen
- B) Formation of fruit
- C) Formation of seed
- D) Growth of plant

3. **Analyzing Each Option**:
- **A) Transfer of pollen**: This is the process of pollination, where pollen grains from the male anther are transferred to the stigma of the female flower. This is indeed a pre-fertilization event as it facilitates the meeting of male and female gametes.
- **B) Formation of fruit**: This occurs after fertilization when the ovary develops into a fruit. Hence, it is a post-fertilization event.
- **C) Formation of seed**: This also occurs after fertilization when the fertilized ovule develops into a seed. Thus, it is a post-fertilization event.
- **D) Growth of plant**: This refers to the overall growth processes of the plant, which are not specifically tied to the fertilization process.

4. **Conclusion**:
- The only option that represents a pre-fertilization event is **A) Transfer of pollen**. This is essential for the fertilization process to occur.

### Final Answer:
**A) Transfer of pollen**
