a. physical change
b. chemical change

Explanation:

A physical change involves a change in the state or appearance of a substance without altering its chemical composition. When phosphorous dissolves in carbon disulfide, it is just a dissolution process. There is no new substance formed. In a chemical change, new substances are formed through chemical reactions. Since no new chemical species are created here, it is a physical change.
