Sugar present in DNA is

• 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.
