Solution
The correct option is B Primary and secondary cell wall
The cell wall is made up of the primary wall, which is formed when the cell is young. This then gets either replaced or the secondary wall is added inside it towards the cell membrane. Sometimes, a tertiary cell wall is also formed in some plant cells. This is the innermost layer of the cell wall and is thin. It may not be present in all cells.
The middle lamella is the layer that is first formed during cytokinesis stage (division of cytoplasm) of cell division and the additional layer that is formed after that is the primary cell wall.
