Answer

Brief Explanations:

A chemical change involves bond - breaking and new substance formation, and is irreversible (Statement I). A physical change means the substance remains the same, no bonds are broken, and it is reversible (Statement III). Statement II is incorrect as re - ordering intermolecular forces is more related to physical changes. Statement IV is incorrect as permanently altering the substance's makeup is characteristic of a chemical change. So, statements I and III best elaborate the difference.

Answer:

A. I & III
