All reducing sugars are muatrotating. Although (IV) is an $α$ -hydroxy ketone and hence reducing but it can’t mutarotate as it is not a carbohydrate, can’t form ring. In (II) the glycosidic linkage is in between two anomeric carbons and hence ring opening can’t occur, thus non reducing as well as non – mutarotating.
