Marginal meristem is the meristem located along the margin of a leaf primordium and forming the leaf blade. The apical meristem or growing tip, is a completely undifferentiated meristematic tissue found in the buds and growing tips of roots in plants.
Intercalary meristems are capable of cell division, and they allow for rapid growth and regrowth of many monocots. Intercalary meristems at the nodes of bamboo allow for rapid stem elongation, while those at the base of most grass leaf blades allow damaged leaves to rapidly regrow.
In mass meristem the cells divide in all planes to form bulk of tissue. this type of meristem takes part in the formation of cortex, pith, endosperm and sporangia.
Therefore, the correct answer is option D.

Meristem present at the lamina margin is Marginal meristem.
Explanation:
The margin of a leaf is the edge or border of the leaf. It is the outermost part of the leaf lamina. The meristem present at the lamina margin is called the marginal meristem.
The marginal meristem is responsible for the growth and development of the leaf margin. It is involved in the formation of new cells and tissues at the leaf edge. The cells produced by the marginal meristem differentiate into various specialized cell types, such as epidermal cells, stomata, trichomes, and glandular structures.
Functions of Marginal Meristem:
1. Leaf Margin Elongation: The marginal meristem is responsible for the elongation of the leaf margin, leading to the expansion and growth of the leaf lamina.
2. Differentiation of Leaf Structures: The cells produced by the marginal meristem differentiate into specialized cell types that contribute to the overall structure and function of the leaf. For example, the epidermal cells form the outer protective layer of the leaf, stomata help in gas exchange, trichomes provide defense against herbivores, and glandular structures secrete substances.
3. Leaf Margin Complexity: The marginal meristem plays a role in determining the complexity of the leaf margin. It controls the formation of lobes, teeth, or serrations along the leaf edge, giving each species a unique leaf shape.
4. Leaf Margin Repair: The marginal meristem can also repair any damage or injury to the leaf margin. It can produce new cells to replace the damaged ones and restore the integrity of the leaf edge.
In conclusion, the meristem present at the lamina margin is the marginal meristem. It is responsible for the growth, differentiation, complexity, and repair of the leaf margin.
