Answer & Solution
Correct answer: B. cambium forming from mature parenchyma
Mature parenchyma cells in the stem can regain dividing ability and form the interfascicular cambium; a textbook case of dedifferentiation. Cork cambium (phellogen) is similar. Leaf shedding, germination and stomatal movement are different physiological processes.
