Answer» Gram +ve bacteria have well inner layered membrane (i.e plasma membrane & peptidoglycan),but no lipid layer outer membrane. Gram +ve cell have thick,homogeneous cell wall made up of murine & mucopeptide. And, even they a large amount of teichoic acid found in cell wall,and extend to peptidoglycan layer Therefore,the ans is [D] all the above are correct
