Solution

The correct option is B Lateral
Secondary growth results in an increase in girth or diameter of the stem by formation of secondary tissue (secondary phloem and secondary xylem) by the activity of lateral meristem. Secondary growth is controlled by the two lateral meristems - the vascular cambium and the cork cambium.
