a. chemical change
b. physical change

Explanation:

Melting is a process where a solid turns into a liquid. In a physical change, the substance's chemical composition remains the same. When sodium melts, it is still sodium, just in a different state (from solid to liquid). A chemical change would involve a reaction where new substances are formed.

Answer:

B. physical change
