I believe it's D <span>.DNA repair enzymes often repair errors.
</span>I believe this because enzymes<span> remove incorrect bases with a few surrounding bases, which </span>are<span> replaced with the </span>correct<span> bases with the help of a DNA polymerase and the template DNA. When replication mistakes </span>are<span> not corrected, then it may result in </span>mutations<span>, which sometimes </span>can<span> have serious consequences.</span>
