Correct:
A
Explanation
Intercalary meristems are a type of primary meristematic tissue located at the base of leaves or internodes. Unlike apical meristems, which are found at the tips of stems and roots to facilitate primary elongation, intercalary meristems are positioned between regions of mature, permanent tissues. This specific location allows for rapid vertical growth and the elongation of internodes, which is particularly vital in monocots like grasses. This positioning serves as an evolutionary adaptation, enabling plants to regrow quickly after being grazed by herbivores or cut, as the growth tissue remains protected at the base rather than being lost at the terminal tip. In some species like mint, these meristems are specifically found below the nodes.
