B. One

because an independent variable is something you change. So in a scientific experiment you only change one thing. If you happen to change more than one thing then the test becomes unfair therefore you should repeat and make sure that only one thing is changed this time.

DNA, RNA, and starch: What do these three important biomolecules have in common? A) They all contain at least one carboxyl group
Norma-Jean [14]

Answer: The correct answer is -

B) The presence of at least one carbon-based sugar.

Explanation:

RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are the two types of nucleic acids that are composed of nucleotide (monomer of nucleic acid).

A nucleotide has three parts, which are pentose sugar (5 carbon sugar), nitrogenous base, and phosphate group.

Starch is a complex carbohydrate as it is composed of several units of simple sugar such as glucose.

Thus, the presence of at least one carbon-based sugar is common in DNA, RNA, and Starch.
