    The answer to your question is letter B.

    Explanation:

    Decomposition reaction: is a kind of chemical reaction where one reactant yields 2 or more products.

    Redox: is a kind of chemical reaction where there is a change in the oxidation numbers of some reactants and products.

    Double-displacement: is a kind of chemical reaction where two reactants interchange cations and anions.

    Acid-base: in this chemical reaction an acid and a base react to yield a salt and water.

    According to this information, the reaction given is:

    a) it is not a decomposition reaction because it has two reactants.

    b) Redox because Zn and Cu changed their oxidation numbers.

    c) It is not a double-displacement reaction because "Zn" does not have an anion.

    d) It is not an acid-base reaction because the products are not water and salt.
