Answer:

Option B

Explanation:

Topoisomerase are the enzymes that help in correcting the underwinding of DNA. It act as a maintainer of DNA replication process by preventing the overtightning of the DNA double helix at the time of replication. The DNA helix which is infront of the replication fork is prevented from getting tight at the time of unwinding which is a problem arising due to the double-helical structure of DNA.

Hence, option B is correct
