No, option D is correct because teichoic acids are not present in gram-positive bacteria.

In these options, option A should not be there if 'd' is the correct answer.

Because gram + bacteria is single but thick-walled, whereas gram - bacteria has 3 layered cell wall.

Other options are correct.

Why isn't the answer B?

Only peptidoglycan is thicker in gram positive bacteria, gram negative contains lipopolysaccharides, phospholipids, thin layer of peptidoglycan even though all these lack in gram positive. Gram negative has more components and is thus thicker.

Why the answer is option 'D'?

In gram positive bacteria only peptidoglycan exits where teichoic acid is present and the peptidoglycan layer is more thicker than gram negative bacterial call wall.

Why all of these the gram positive not have multiple layers?
