Bacteria are considered more as plants than animals because of the presence of

The correct option is B Cell wall
Bacteria belong to group Monera. Organisms belonging to group Monera are primitive, unicellular and prokaryotes.

Each and every organism (except viruses) contain DNA as their genetic material. Hence, option A is incorrect.
According to cell theory, each cell is bounded by the plasma membrane. Plasma membrane is the outer covering of the cell which protects the cell. It also supports the framework of the cell. Therefore, option B is incorrect.
Bacteria being prokaryotes do not contain membrane bound organelles like mitochondria. Plant cells being eukaryotes contain mitochondria. Hence, option D is incorrect.
Both, plant cells and bacteria contain cell wall surrounding the cell membrane. Plant cell wall is made of cellulose lignin. Bacterial cell wall is made of peptidoglycan which is in turn made of derivatives of sugar as N- acetylglucosamine and N-acetylmuramic acid which are covalently attached to the core protein. Therefore, bacteria is said to be more like plant cell than animal cell. Therefore, option C is correct.
