Correct Option: D. Separating cotton fibre from its seed Explanation of the Correct Answer: Ginning is a crucial process in the cotton industry that involves separating the cotton fibers from the seeds. This process is essential because it prepares the cotton for further processing into textiles and other products.

1. Understanding Ginning:
2. Ginning is the mechanical process that removes the seeds from the cotton bolls (the protective capsules that contain the cotton fibers).
3. The primary goal of ginning is to produce clean cotton fibers that can be spun into yarn or thread, while also collecting the seeds for other uses, such as oil extraction or planting.
4. Importance of Ginning:
5. The quality of the cotton fiber is significantly influenced by the ginning process. Proper ginning ensures that the fibers are not damaged and that they are free from impurities.
6. The seeds that are separated can be processed to extract cottonseed oil, which is a valuable product in the food industry and for industrial uses.

Why the Other Options are Incorrect:

• Option A: Extracting cotton seed oil
• This option is incorrect because ginning does not involve the extraction of oil. While cotton seeds can be processed to extract oil after ginning, the ginning process itself is solely focused on separating the fibers from the seeds. Therefore, this option misrepresents the primary function of ginning.
• Option B: Separating fibres from the bark of kena
• This option is incorrect as it refers to a different plant and process. Kena (or kenaf) is a different fiber plant, and the process of separating fibers from its bark is not related to cotton ginning. Ginning specifically pertains to cotton and does not involve any other plant materials.
• Option C: Grinding cotton seeds
• This option is also incorrect. Grinding cotton seeds is a separate process that occurs after ginning if the seeds are to be processed for oil extraction or meal production. Ginning itself does not involve grinding; it is about separation.

Summary of Key Points:

• Ginning is the process of separating cotton fibers from their seeds.
• It is essential for producing clean cotton for textile manufacturing.
• The seeds can be used for oil extraction or planting after ginning.
• Understanding the ginning process is crucial for anyone involved in the cotton industry.

Revision Summary:

• Ginning separates cotton fibers from seeds, preparing them for textile production.
• It does not involve oil extraction or processing of other plants.
• The quality of ginning affects the final product's quality.
• Ginning is a vital step in the cotton supply chain, impacting both fiber and seed utilization.
