    because it contain 5 d-orbitals.

    Explanation:

    unlike alkali and alkaline earth metals, transition metals have 5d-orbitals. electrons are around the nucleus some are away and some are close to it. Electrons change their energy levels at suitable conditions and as transition metals having 5-d orbitals so its electrons can easily goes to other transition state thus causing multiple oxidation states.
