Given below are two statements: Statement I: RNA mutates at a faster rate. Statement II: Viruses having RNA genome and shorter life span mutate and evolve faster. In the light of the above statements, choose the correct answer from the options given below:
RNA is unstable and mutates faster, so RNA viruses with short life spans evolve faster.
RNA mutates at a faster rate because it is unstable. Therefore, viruses having RNA genome and shorter life span mutate and evolve at faster rates.
