Solution

The correct option is A Apical meristem
A meristem is a tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place. Meristematic cells give rise to various organs of a plant and are responsible for growth. Apical meristem is a meristem at the tip of a plant stem and root that produces auxin and brings elongation in stem and roots. Growth that originates in the apical meristem is called primary growth.
So, the correct answer is 'Apical meristem'.
