Solution

The correct option is A epidermal cells, stomata and guard cells, each with one nucleus and many chloroplasts.
A well-stained leaf peel shows nuclei in a high power microscope. The leaf peel possesses stomata, guard cells and epidermal cells. The nuclei are present in both epidermal and guard cells, but stomata do not possess any nucleus.
So A is the correct option.
