    Answer : Option C

    Explanation :

    Since entropy change of mixing is (Δs)mix=−nR∑xilnxi
    So, it is dependent on both number of moles and composition as we can see physically also that more and more number of moles we add to the system the system behavior changes and the properties changes.
