A change can be defined as:

• A. Difference in state of affairs.
• B. Similarity in state of affairs.
• C. Chemical phenomenon of knowing something.
• D. Physical phenomenon of asking questions.

Answer 1

The correct option is A

Difference in state of affairs.

Change is defined as the difference in state of affairs.

For e.g. when ice cream melts, its shape and size become different, so it's a change. Hence when change occurs, all the products that undergo the process show some change in their physical or chemical properties.
