Answer:
water
Explanation:
as guard cell become hypertonic due to higher concentration of starch which is synthesized by the process of photosynthesis as guard cell has chloroplasts.Then water always moves from hypotonic region to hypertonic region , so water moves into guard cell.consequently guard cell become turgid and widens and thus Stomata get open.

The entry of water inside the guard cell opens the stomata.
Option 4
Explanation:
- the turgidity theory of the opening and closing of the stomata explains that the guard cell opens when there is entry of water inside the guard cell. Due to this process there is is endosmosis in the guard cell
- hence the cell becomes enough turgid resulting in the opening of the small for which is known as the stomata.
