If the normal is doubled there will be no change in coefficient of friction, as it only depends upon the nature of pair of surface in contact. So doubling the normal will just double the frictional force and will not affect the coefficient of friction

(D) NOT CHANGED as the Normal Force has nothing to do with the frictional force as they are perpendicular .
