Correct answer: (1) A
Explanation:
The correct record is made by student A as X represents stoma whereas Y represents guard cells.
Stoma also known as the stomatal pore is an opening which is surrounded by a pair of guard cells.
Guard cells are bean shaped cells which regulate the opening and closing of the stomatal pore.
