The correct option is B DNA replication
Okazaki discovered the way in which the lagging strand of DNA is replicated via fragments by conducting an experiment using E. coli named the strand Okazaki fragment. Okazaki fragments are the fragmented piece of newly synthesized DNA strand called as lagging strand during DNA replication. They are complementary to the lagging template strand, together forming short double-stranded DNA sections. Hence option C is correct.
