The ones yielding two monosaccharides on hydrolysis are:

Correct answer: D. Disaccharides

  • A. Trisaccharides
  • B. Tetrasaccharides
  • C. Pentasaccharides
  • D. Disaccharides

Explanation

The correct answer is D. Disaccharides are composed of two linked monosaccharide units, and upon hydrolysis, they yield exactly two monosaccharides. This is why they fit the description given in the question. Trisaccharides, tetrasaccharides, and pentasaccharides contain three, four, and five monosaccharide units respectively, and their hydrolysis results in the release of the corresponding number of monosaccharides, not just two.
