Carbolic reactions breaks larger substances to smaller ones.
Anabolic reactions forms larger compounds from smaller units.
DNA synthesis does not involve breaking down of sugars.
Dehydration is a umbrella term used for reactions that releases water as a byproduct. In the case of sugars, they are held by Glycosidic bonds. To break them, hydration is needed as 1 water molecule breaks 1 glycosidic bond. The process of forming large units of sugars involves dehydration to form the glycosidic bonds. Therefore option d is wrong.
DNA guiding production of protein is definitely wrong as this process doesn't cause sugars to break down at all.
