Solution

The correct option is B Plasma membrane
The structure of an idealized bacterial cell wall contains an outer layer or cell envelope which further has two components - a rigid cell wall and beneath it a cytoplasmic or plasma membrane. The cell envelope encloses the protoplasm, comprising the cytoplasm, cytoplasmic inclusions such as ribosomes and mesosomes, granules, vacuoles and the nuclear body. Some bacteria may possess cell enclosed in a viscid layer, which may be a loose slime layer organised in a capsule (glycocalyx) to keep it (the cell) moist.
So, the correct option is 'Plasma membrane'.
