Detailed Solution

  • The basic formula of monosaccharides has five carbon atoms called Pentose. 
  • Hereditary materials, for example, DNA and RNA present inside the ribose sugar, are a combination of five-carbon sugars and connects the nitrogenous bases at the primary carbon atom on the ring.
  • Deoxyribose sugar is present in the DNA, and ribose sugar is present in the RNA.
  • Heptose is a monosaccharide with seven carbon atom rings.
  • Hexose is a monosaccharide with six carbon atom ring.
  • Tetrose is a monosaccharide with four carbon atom ring.

Hence, option D is the correct answer.
