Solution

The correct option is B If both assertion and reason are true but reason is not the correct explanation of assertion
Secondary growth is the result of the activity of the two lateral meristems, the cork cambium (phellogen) and vascular cambium.
Vascular cambium is formed from conjunctive parenchyma cells lying just below each phloem strand. The cells of pericycle lying outside the protoxylem also become meristematic to form part of strips of cambium

Therefore, both assertion and reason are true but reason is not the correct explanation of assertion .
