Explanation / Answer
Answer : D. Lagging strands are synthesized as Okazaki fragments.
Explaination : Lagging strand is the strand formed during replication of DNA which synthesized in opposite direction to replication fork and due to which the DNA fragments are synthesized known as Okazaki fragments. Hence only D option is correct because DNA polymerase I present in prokaryotes and DNA polymerase present in Eukaryotes.
