A Correct answer
Explanation

It is the meristem, that occurs laterally, parallel to the long axis, of plant body. Cambium strips formed in the vascular bundles, and in the cortex, are common examples of lateral meristem. It is responsible for an increase in the girth (circumference) of the plant body, as it brings about the formation, of secondary permanent tissues.
