Explanation:

Let's choose plastics. Plastics are polymers made from repeating monomer units. One way they are useful in daily life is in packaging. Plastics are lightweight, durable, and can be molded into various shapes, which makes them ideal for storing food, beverages, and other consumer goods. They protect the contents from damage, contamination, and help in preserving the freshness of food items. For example, plastic bottles are used to package water, soft drinks, and other liquids, providing a convenient and leak - proof container that is easy to transport and store.

Answer:

Plastics are useful in daily life for packaging (e.g., plastic bottles for storing liquids, protecting and preserving contents).
