Solution

The correct option is C Ribozyme
RNA is another nucleic acid apart from DNA which contained building blocks very similar to DNA. Hence,biologists recognized earlier that RNA could store information in its linear sequences. With the discovery in the 1980s that RNA molecules were capable of biological catalysis, a function till now ascribed to proteins alone, RNA took on the role of the single entity that could act as both chicken and egg. Within a few years of the discovery of these catalytic RNAs (ribozymes), scientists had formulated an RNA hypothesis that posited an early phase in the evolution of life where all key functions were performed by RNA molecules.
Thus, the correct answer is option B.
