Answer 1

Correct choice is (a) Neosugar

To explain I would say: Neosugar is a low cariogenic sweetener, which consists of a mixture of glucose, sucrose and β-2,1 linked fructans with terminal non-reducing glucose residues. Xylosucrose is β-D-fructofuranose-(2,1)-a-D-xylopyranoside which is synthesized by fructosyltransferases. Lactose is a disaccharide made up of glucose and galactose. Sucrose is also a disaccharide made up of glucose and fructose.
