Answer 2

c) Water in guard cells

Step-by-step explanation:

Stomata is surrounded by specialized cells known as guard cells. They are two kidney shaped cells and function to open and close stomatal pores. Stomata allow a plant to take in carbon dioxide for photosynthesis. So, they are generally open by day and closed at night.  They also help to reduce water loss by closing when conditions are hot or dry.  The opening and closing of stomata is governed by increases or decreases of solutes like potassium in the guard cells, which cause them to take up or lose water, respectively.

Option C is the answer.
