Solution

The correct option is D Without cell wall
Protoplast is a cell that does not have a cell wall. The cell wall is removed completely mechanically or enzymatically. They are derived from gram positive bacteria. They are used to study membrane biology, or for DNA transformation as there is no cell wall to block the passage of DNA.
Option B is correct.
