A Correct answer
Explanation

Stomata are microscopic pores primarily found on leaf surfaces that serve two critical functions: gas exchange (CO2 intake for photosynthesis, O2 release) and transpiration (water vapor loss). Option B describes xylem function, and option C describes phloem function. Stomata open and close via guard cells to balance these processes.
