The correct option is C Trehalose
Sugar which found in haemolymph of insects is called trehalose. Trehalose, also known as mycose or tremalose, is a natural α-linked disaccharide. It can be synthesised by bacteria, fungi, plants and invertebrate animals. It is implicated in anhydrobiosis: the ability of plants and animals to withstand prolonged periods of desiccation.The sugar is thought to form a gel phase as cells dehydrate, which prevents disruption of internal cell organelles, by effectively splinting them in position.
