The Correct Option is C

Solution and Explanation

textbf{Step 1: Maltose.}
Maltose is a disaccharide composed of two glucose units connected by an alpha-1,4-glycosidic bond. It is a reducing sugar because it has a free anomeric carbon that can open to form an aldehyde group, which can reduce other compounds. Thus, Statement-1 is incorrect. Step 2: Lactose.
Lactose is a disaccharide made up of glucose and galactose, linked by a beta-1,4-glycosidic bond. It is a reducing sugar because the glucose unit has a free anomeric carbon, allowing it to open into an aldehyde group. Therefore, Statement-2 is correct. \[ \boxed{\text{Statement 1 is incorrect but statement 2 is correct.}} \]
