According to the modern theory of stomatal opening proposed by Levitt, the pH of guard cells can rise due to A. CO2 assimilation by guard cells only B. Active efflux of H+ ions by guard cells C. Conversion of starch into PEP D. Active uptake of K+ in guard cells

Answer
The pH rise in guard cells is due to active uptake of K+ ions into the cells, which causes water to enter by osmosis, leading to stomatal opening.
