The correct option is
C Circular
A genome is the complete set of genes in an organism. Bacteria is a prokaryotic organism. It has single, circular DNA. The bacterial genome leads ranges from 130 kbp to 14 Mbp. The genetic material is in direct contact with the cytoplasm. The region of the cytoplasm where the genetic material is present is known as the nucleoid. The circular DNA undergoes transcription and translation and synthesizes bacterial proteins.
So, the correct answer is option A.
