Hint: Let us first understand what is cell division. The process that involves the parent cell into daughter cells is called cell division. Active cell division is a potential cell division where a cell is divided into multiple new cells that results in the growth of the plant in the meristematic tissue.

Complete Answer:
Meristematic tissues are found at the tips of the stems and roots. These kinds of meristematic tissues are known as apical meristems. The active cell division occurs at the tips of stem and root which leads to the elongation of cells that give rise to a new primary tissue.

Additional information: Meristematic tissues are also present in the base of the internodes as well as leaves. These types of meristematic tissues are called intercalary meristems. These are responsible for the formation branches.
Meristematic tissues present on the sides of root and stems are called lateral meristems. They are responsible for the increase in the girth of plants.

Hence the correct solution is (B) At the tips of roots and stems.

Note:Active cell division is also called mitotic cell division. Mitotic cell division has four phases. They are prophase, metaphase, anaphase and telophase.
