Answer:
The correct option is C) Apical meristem
Explanation:
Apical meristem can be described as undifferentiated meristematic cells found in the tips of the shoots and roots. The main function of the apical meristem is to start the process of cell division at these parts. In the apical meristems, cells tend to grow by undergoing numerous mitotic divisions. As result, primary growth and lengthening of the plant occur. Hence, the correct option is option C.
Other options, like option B, is not correct because it is the site where secondary growth occurs.
