DNA replication involves the activity of various enzymes. Which of these enzymes is correctly paired with its function?

After Searching for the options since you never provided any I found the following similar question options:

a. dna polymerase-separates the dna helix

b. dna ligase-links new nucleotides to original base

c. dna polymerase-adds new nucleotides to the growing dna strand

If these were your options then C is the correct answer for you.
