Best answer
The correct choice is (a) Faster rate

For explanation: Mutations can be seen in both DNA and RNA. But RNA mutates at a much faster pace in comparison to the DNA. This is due to the lack of stability that is seen in RNA. Likewise, the viruses which contain RNA as their genetic material also mutate at a faster rate. Their life span will stand short on the contrary.
