The answer is D. Prokaryotes have one origin of replication but it proceeds in two directions.
Explanation:
DNA replication is a process in which in which one parental DNA strand acts as template to synthesize complementary daughter strand. There are specific sequences in DNA from where replication starts. These sequences are called origin of replication. In Eukaryotic cells due to large number of DNA many origins of replication are present. However, in prokaryotic DNA only one origin of replication is present that is bi-directional.
