    I understand why its not C or D because they are aldehdyes which can be further oxidised to carboxylic acids. But I dont understand why B cannot be oxidised but A can when it is also a ketone which cant be oxidies any further.Attachment 586534586536

    You're correct in that A and B both have ketones and these won't be further oxidised, but each also has an alcohol group, think about which of these can be oxidised, drawing the product should definitely help
