b.Sugar transport



c. Active transport



d. Osmosis

Answer 1

K+ exchange is the answer

Answer 2

Modern theory of stomatal opening is K+ exchange.

Hence the correct answer is option A. Guard cells can be referred as the cells surrounding every stoma.

It helps for regulating the transpiration rate by closing and opening of the stomata.

The function of stomata is generally caused by accumulation of the K+ (the potassium ions) in case of the guard cells.
