Solution

The correct option is A Youngest secondary phloem
Vascular cambium divides during secondary growth of the plant and produces secondary xylem towards the central axis of the stem and phloem add up towards the outside and is known as the cambial zone.
So the correct option is 'Youngest secondary phloem'.
