b. to support the extra weight of the tree due to an increase in its breadth and to prevent it from collapsing
c. to support the roots due to an increase in their number and to prevent the tree from collapsing?

Answer is option A

Explanation:

Secondary growth is the increase in girth of roots and stem of the plants by dividing lateral meristems cells and produce secondary tissues. Secondary growth is important to woody plants as woody plants are way taller than other plants and need more support in roots and stems. The secondary growth can be seen as annual rings in woody plants.
