• B. Cell membrane.
• C. Guard cells.
• D. All of these

Answer 1

The correct option is C

Guard cells.

The correct option is C.

An explanation for the correct answer:

• Stomata are pores that are present on the surface of most higher plants' aerial sections.
• A specialized cell termed a guard cell surrounds each stoma. These cells assist in the regulation of transpiration by opening and shutting stomata.

The explanation for the incorrect options:

Option A:

• Plant cells have a cell wall protecting their plasma membrane and providing tensile strength.

Option B:

• A cell's protoplasm is surrounded by the cell membrane.

Option C:

• The cell wall and cell membrane options are wrong, so this option is incorrect.

Therefore, the stomatal pores are surrounded by guard cells.
