Solution
The correct option is B A pair of guard cells.
Stomata are small elliptical openings on leaves
that contain chloroplasts. They are girdled by two-kidney shaped cells known as

inner wall and a thin outer covering which control the closing and opening of
the pores of stomata.
So, the correct answer is option B.
