Answer & Solution
Correct answer: A. Apical meristem (at the root tip)
Apical meristems sit at the tips of roots and shoots.
Their division pushes the tip forward (in roots: downward into the soil), increasing length.
If you cut off the root tip, longitudinal growth stops — which is why pruning a plant tip stunts vertical growth.
