3. Both meat (such as beef, chicken, and pork) and fish (like tuna, salmon, and sardines) are commonly canned to provide convenient, long-lasting food options for consumers.
4. Nutritional Value:
5. Canned meat and fish retain much of their nutritional value, making them a popular choice for consumers looking for protein-rich foods that are easy to store and prepare.
6. Market Demand:
7. There is a significant market demand for canned meat and fish products, as they are often used in various cuisines and are staples in many households.

Explanation of Why Other Options Are Incorrect: B. Cotton and Sea: - Cotton is a fiber crop used primarily in the textile industry, while "sea" is not a specific raw material. This option does not relate to food preservation or the canning industry. C. Hide and Skin: - Hides and skins are by-products of animals used primarily in leather production. While they are important in other industries, they are not used in the canning process, which focuses on food preservation. D. Pulpwood and Cocoa: - Pulpwood is used in the paper industry, and cocoa is primarily used in chocolate production. Neither of these materials is relevant to the canning industry, which is focused on preserving food items. Summary of Key Points:

• The canning industry primarily uses perishable food items like meat and fish for preservation.
