the pentoses, ribose, deoxyribose form integral parts of
a. glycogen
b. hexose monomers
c. sucrose
d. RNA and DNA (I think this is correct but can't see pentose where pentose is invloved. HOW???)

Both DNA and RNA are composed of units called nucleotides.
Each nucleotide is composed of a pentose sugar, phosphate and one of the four nitrogenous bases.
Pentose simply means 5-carbon sugar.
In RNA the sugar is ribose and in DNA the sugar is deoxyribose. This is due to the absence of one oxygen atom in deoxyribose. But both are 5-carbon sugars, that is, pentose.

The answer is D. The term pentose refers to the fact that deoxyribose/ribose each have 5 carbons in their respective sugars. Hexose sugars have 6 carbons.
Pentose is an integral part of the nucleotide sequences of RNA and DNA. Each nucleotide is composed of a phosphate group, a pentose sugar (ribose/deoxyribose), and a nitrogenous base pair (adenine, guanine, cytosine, and thymine).

its because DNA is made up of a nitrogenous base, a phosphate group and a Pentose sugar (five carbons).
Please give me best answer- ive never had it!
