Answer 1

The correct option is C

Materials are grouped for fun.

The explanation for the correct option:

1. Materials are grouped for entertainment purposes.
2. Materials are typically organized into groups to study their properties and applications in a systematic manner. As a result, materials are not grouped for fun.
3. Classification or sorting of materials is not done for fun.

Hence, option (C) is correct.

The explanation for incorrect options:

1. The materials are not grouped for the sake of amusement. They're grouped together for a reason. Materials are typically organized into groups to study their properties and applications in a systematic manner.
2. When items are organized, they are easier to store and retrieve in the correct order.
3. When they're organized, it's also easier to analyze their properties and retain and apply that information.
4. Materials can be classified on the basis of their uses, colors, appearance, state, and size.

Hence, options (A),(B), and (D) are incorrect.
