Which of the following are all disaccharides?

Correct answer: A. Maltose, Sucrose, Lactose

  • A. Maltose, Sucrose, Lactose
  • B. Glycogen, Lactose, Sucrose
  • C. Maltose, Lactose, Glucose
  • D. All of the above

Explanation

The correct answer is Option A: Maltose, Sucrose, Lactose. Each of these is a disaccharide, composed of two linked monosaccharides. Maltose consists of two glucose molecules, sucrose is made of glucose and fructose, and lactose is composed of glucose and galactose. Option B is incorrect because glycogen is a polysaccharide, not a disaccharide. Option C is incorrect because glucose is a monosaccharide, not a disaccharide. Option D is incorrect because not all options are correct; only Option A includes only disaccharides.
