GPT-4o mini · Answer

The correct option is:

A. Burning toast is a chemical change; straining orange juice is a physical change.

Burning toast involves a chemical reaction, where the toast undergoes combustion, resulting in new substances (like carbon).
Straining orange juice is an example of a physical change, as it involves separating the pulp from the juice without changing the chemical composition of the juice itself.
