a)Swollen

Explanation:

Guard cells are the kidney-shaped cells which surroundeach stoma.They are incharge of opening and closing of stomata for transpiration and exchanging of gases. The guard cells widened when they are turgid, or swollen. This turgidity is due to the accumulation of K+ ions. Pottasium moves into the vacules .The water moves into the vacuoles, following potassium ions. As a result, the guard cells expand and the stoma opens/widens.Hence option a ) is correct.
