Answer:
A. Gram positive bacteria
Explanation:
Gram-positive bacteria have the cell wall that consists of a single thick layer of peptidoglycan. This peptidoglycan layer is 20-80 nm thick in Gram-positive bacteria. On the other hand, the peptidoglycan layer in cell walls of Gram-negative bacteria is only 2-7 nm thick.
The thicker peptidoglycan layer of Gram-positive bacterial cells makes them more resistant to osmotic stress than the Gram-negative cells.
I think the answer is B
Hope this helps!!!:)
