Some organic compounds are given below:Select the correct statement(s) about the above compounds from the following:

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.
