2 Male gamete, ovary
3 Vegetative cell, style
4 Tube cell , stigma

Options

A. Pollen tube, style
B. Male gamete, ovary
C. Vegetative cell, style
D. Tube cell , stigma

Answer

To answer the question, we need to analyze the process of pollen grain germination and the structures involved in the reproduction of flowering plants.

### Step-by-Step Solution:

1. **Understanding Pollen Grain Germination**:
- Pollen grains are the male gametes of flowering plants. When they land on the stigma (the receptive tip of the pistil), they begin to germinate.

2. **Formation of the Pollen Tube**:
- Upon germination, the pollen grains develop a structure known as the pollen tube. This tube is essential for the transfer of male gametes to the ovule for fertilization.

3. **Growth Path of the Pollen Tube**:
- The pollen tube grows down through the style, which is the elongated part of the pistil that connects the stigma to the ovary. The style serves as a passage for the pollen tube to reach the ovary.

4. **Final Answer**:
- Therefore, the correct completion of the statement is: "The pollen grains germinate on the stigma and resulting in **pollen tube** formation which grows through the **style**."

### Correct Option:
1. Pollen tube, style
