Cane sugar contains glucose and fructose so it is a disaccharide.


Lactose contains glucose and galactose so it is a disaccharide.

Maltose contains glucose and glucose so it is a disaccharide.

Raffinose contains 1 unit of glucose, 1 unit of fructose and 1 unit of galactose so it is not a disaccharide. It is a trisaccharide.
 
Option B is correct.
