Step-by-step explanation:
The correct answer is d. tearing.
Tearing is an example of a physical change, which involves a change in the physical properties of a substance without any change in its chemical composition. In this case, tearing involves the physical separation of a material into two or more pieces without any change in its chemical makeup.
The other options are examples of chemical changes, which involve a change in the chemical composition of a substance. Rusting (a) is a chemical change that occurs when iron reacts with oxygen in the presence of water to form iron oxide. Bubbles or fizzing (b) can be a sign of a chemical change, such as when an acid reacts with a base to form a salt and water. Unexpected temperature change (c) can also be a sign of a chemical change, such as when a substance undergoes a combustion reaction and releases heat.
