Answer:
(B) DNA polymerase recognizing a "mismatched" base pair, like adenine and guanine.
Explanation:
In DNA, adenine is always paired with thymine and guanine with cytosine. The DNA polymerase has 3' to 5' exonuclease activity which is also called proofreading activity. If a DNA polymerase adds the wrong nucleotide, it can not be translocated post the mismatched nucleotide. The pause allows the 3' to 5' exonuclease activity of DNA polymerase to remove the mismatched nucleotide followed by the addition of a correct nucleotide.
