Answer:
Correct Answer: B
Solution:
Some of the outer cells of the root hair zone give rise to lateral tubular outgrowths called root hairs.
As the cells of the root hair zone becomes mature, the root hairs shrivel and become non-functional.
However, new root hairs are formed in the older part of the zone of elongation.
