Given below are two statements:
Statement $I$: In the $\text{RNA}$ world,$\text{RNA}$ is considered the first genetic material evolved to carry out essential life processes. $\text{RNA}$ acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive,$\text{RNA}$ is unstable.
Statement $II$: $\text{DNA}$ evolved from $\text{RNA}$ and is a more stable genetic material. Its double helical strands being complementary,resist changes by evolving a repairing mechanism.
In the light of the above statements,choose the most appropriate answer from the options given below:

• A
  Both statement $I$ and statement $II$ are correct.
• B
  Both statement $I$ and statement $II$ are incorrect.
• C
  Statement $I$ is correct but statement $II$ is incorrect.
• D
  Statement $I$ is incorrect but statement $II$ is correct.
