Answer is: C. forming or breaking bonds.

In a chemical reaction, chemical bonds are forming and breaking and this cause the transformation of one group of chemical substances to another

For example synthesis of water from its elements: 2H₂ + O₂ → 2H₂O, nonpolar bonds between hydrogen and oxygen atoms are breaking and new polar bonds are forming between hydrogen and oxygen in molecule of water.
