During drought conditions, abscisic acid is used to close stomata. Using what you know about stomata opening this could be accomplished by... actively transporting water into guard cells triggering potassium transport into guard cells allowing water to enter the guard cells by osmosis triggering potassium transport out of guard cells

Solution

During drought condition the plants could be treated with abscisic acid to decrease the transpiration from the stomata by maintaing the stomata closed.

this led by: loss of K + ions from guards cell

increased water potential

loss of water from guard cells

guard cells become flaccid

stomata closed.

therefore correct option is : (d) k+ is transported out of guard cells.
