Answer 1

Answer: (C)

Helicase is an enzyme that catalyzes breakage of H-bonding between strands of DNA and unwinding it for the process of replication.
Primase is an enzyme involved in the process of DNA replication where it catalyses the synthesis of short RNA segment complementary to the single-strand DNA.
Single strand binding proteins are set of long-chain peptides that bind to the unwinded strands of DNA and hold them in place during the replication process.
Topoisomerase is a ubiquitous enzyme that plays an important role in the DNA replication process. It reduces the torsional strain on the folded DNA structure by removing the supercoils formed in from of the replication fork.
