(d) On the upper surface

I have been asked this question in an international level competition.

The question is from Organisms and Populations topic in division Organisms and Populations of Biology – Class 12

Answer 1

Right answer is (a) Nowhere

For explanation I would say: In submerged hydrophytes stomata are absent. These are true water plants in which plant cells are used to absorb nutrients, water, and dissolved gases in water. Some examples of submerged hydrophytes are Hydrilla, Potamogeton, Utricularia, etc.
