    Answer:

    B Chemical change

    Explanation:

    Something formed with a dark blue colour. It was a new substance with new properties, so this was a chemical change.

    A is wrong because a new substance formed.

    C is wrong because the copper stayed solid.

    D is wrong because they did not say anything about the viscosity of the solution
