Explanation

Correct answer:

Both (A) and (R) is correct but (R) is not the correct expalanation of (A).

Some mycoplasmas (PPLO’S) are named as L-forms where ‘L’ stands for Lister Institute. L-forms can be obtained by treating the bacterial cultures with enzymes like lysozyme or an antibiotic such as penicillin. They lyse the cell walls, due to which small spherical bodies resembling mycoplasmas (PPLO'S) are formed.
