Explanation:
Stem elongation is one of the most important processes that occur in plants. It is the result of the activity of meristems, which are specialized regions of the plant that contain undifferentiated cells that can divide and differentiate to form new tissues.
There are three types of meristems in plants:
1. Apical meristem: It is located at the tip of the stem and roots and is responsible for the primary growth of the plant (lengthening of the stem and roots).
2. Intercalary meristem: It is located between mature tissues and is responsible for the secondary growth of the plant (increasing the diameter of the stem and roots).
3. Lateral meristem: It is located along the sides of the stem and is responsible for the secondary growth of the plant (increasing the diameter of the stem).
In the case of grasses and related plants, stem elongation occurs mainly due to the activity of both apical and intercalary meristems. The apical meristem is responsible for the primary growth of the stem, which results in the elongation of the stem. The intercalary meristem is responsible for the elongation of the internodes (the spaces between the nodes where the leaves are attached), which also contributes to the overall stem elongation.
Therefore, the correct answer is option 'C', both apical and intercalary meristem are responsible for the elongation of the stem in grasses and related plants.

Apical meristem helps in the growth in terms of length and the intercalary meristem increases the girth of the plant. Classical example to understand this is the growth in bamboo( a type of grass; which is both thick and tall)
