The correct option is C grasses
Secondary growth is the growth that results from cell division in the lateral meristems, the vascular cambium and the cork cambium, which causes the stems and roots to increase in girth.
Dicots such as deciduous angiosperms and Gymnosperms, including conifers and cycads, show secondary growth due to the presence of lateral meristems.
In monocots like grasses, due to the absence of lateral meristems secondary growth does not take place.
