**Explanation:**

**Cotton Plant:**
The cotton plant, scientifically known as Gossypium, is a major source of natural fibers used in the textile industry. It is a shrub native to tropical and subtropical regions around the world.

**Fibers from Cotton Plant:**
The fibers of the cotton plant are found in the fruits, known as bolls, which develop after the flowers are pollinated. These fibers are called cotton lint and are used to make various textiles and products.

**Obtaining Fibers from Cotton Plant:**
To obtain fibers from the cotton plant, the following steps are typically followed:

1. **Planting and Growing:** Cotton plants are cultivated in fields. The seeds are sown, and the plants grow under suitable environmental conditions, including sufficient sunlight, water, and nutrients.

2. **Flowering and Pollination:** The cotton plant produces beautiful flowers which eventually give rise to the cotton bolls. These flowers are pollinated by insects, primarily bees, to facilitate the development of fruits.

3. **Fruit Development:** After successful pollination, the flowers transform into fruits called cotton bolls. These bolls contain the developing seeds surrounded by fibers.

4. **Harvesting:** Once the cotton bolls have matured, they are ready for harvesting. Farmers carefully pick the bolls from the plants to collect the fibers.

5. **Ginning:** After harvesting, the cotton fibers need to be separated from the seeds. This process is called ginning. It involves removing the seeds from the cotton bolls, leaving behind the valuable cotton lint.

6. **Processing and Spinning:** The cotton lint is then processed to remove impurities and create long, continuous fibers suitable for spinning into yarn. Various mechanical and chemical processes are employed to clean and prepare the fibers.

7. **Textile Production:** Finally, the processed fibers are spun into yarns, which are then used to produce different types of textiles, such as clothing, sheets, towels, and many other products.

**Conclusion:**
In summary, the cotton fibers used to make textiles are obtained from the fruits of the cotton plant, known as cotton bolls. These fibers undergo several stages of processing to transform them into usable and versatile materials for the textile industry.

Correct answer is D since the cotton plants flower are the particles to make cotton
