(B) The correct answer is $B$. In bacteria,the replication of the circular chromosome begins at a specific site known as the origin of replication $(oriC)$. From this point,the replication forks move in both directions around the circular chromosome,a process known as bi-directional replication. This allows for the rapid duplication of the entire genome.
