D. Four years.

Answer

To answer the question "Female cone of Pinus develops seeds in", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Female Cone**: The female cone of Pinus is referred to as the megastrobilus. This is the structure that is responsible for seed development.

2. **Understand the Role of Ovules**: Within the megastrobilus, there are ovules. These ovules are crucial as they are the structures that will eventually develop into seeds after fertilization.

3. **Process of Fertilization**: The ovules in the megastrobilus are initially unfertilized. During pollination, pollen grains reach the ovule, leading to fertilization where male and female gametes fuse.

4. **Seed Development Timeline**: After fertilization occurs, it takes a significant amount of time for the seeds to develop. Specifically, it takes about three years for the seeds to fully develop inside the female cone.

5. **Conclusion**: Therefore, the correct answer to the question is that the female cone of Pinus develops seeds in three years.

### Final Answer:
The female cone of Pinus develops seeds in three years.
