<h2>A) option is correct </h2>
Explanation:
- RNA is a linear polymer of ribonucleotides
- Sugar in RNA is ribose instead of deoxyribose which is present in DNA
- The four nitrogenous bases present in RNA are adenine, cytosine, guanine and uracil whereas that in DNA are adenine, cytosine, guanine and thymine
- RNA molecules carry genetic information from DNA to proteins, cannot transmit from one generation to next generation as a genetic material
- Due to steric hindrance by the 2'-OH group of ribose sugar, RNA unable to form double helix

A cell is a membrane-bound structure that occurs as a functional independent unit of life (such as in unicellular organisms, e.g. bacteria, protozoa, etc.), or as the structural or fundamental unit in a biological tissue specialized to perform a particular function in multicellular organisms (e.g. plants and animals).
