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.
In exponential growth, numbers increase in value over time in an exponential fashion. In decay, numbers decrease in value over time in an exponential fashion.
