Entropy change of mixing two liquid substances depends upon the

Entropy change of mixing two liquid substances depends upon the Correct Answer Both A and B

Since entropy change of mixing is $${\left( {\Delta s} \right)_{mix}} = - nR\sum {} {x_i}\ln {x_i}$$
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.
