Answer:

b.DNA only in the 3' to 5' direction

Step-by-step explanation:

Since that DNA can only be copied in the 3' to 5' direction, there will be a lagging strand which have to be assembled in short terms called Okazaki fragments, in human a the DNA polymerase is responsible for making the complementary nucleotides, and the DNA ligase enzyme is responsible to link the Okazaki fragments to the lagging strand.
