Anomers are cyclic monosaccharides that differ in configuration only at the acetal or hemiacetal carbon or at the anomeric carbon atoms.
Here, the anmeric carbon atoms are: ‘a’ carbon of glucose and ‘b’ carbon of fructose.
This disaccharide on hydrolysis yields α-glucose and β-fructose.
Thus, option (iii) is correct.
Options (i), (ii) and (iv) are incorrect because ‘a’ carbon of glucose and ‘b’ carbon of fructose are the anomeric carbon atoms.
