Best answer
Right choice is (d) Replication fork

For explanation: In the case of large sized DNA molecules, the double strands of these molecules cannot be entirely separated. This is because, an extremely high amount of energy supply is required. So, in such cases, the process of replication fork takes place. It is a process in which a small opening is made in the portion of the DNA helix for replication to occur.
