To solve this problem, we need to identify the region of the root from which root hairs develop. Let's analyze the regions of the root:$\newline \bullet$Region of Elongation:$\newline$ - This is the area where cells elongate and increase in size.$\newline$ - It is not involved in the formation of root hairs.$\newline \bullet$Root Cap:$\newline$ - This is a protective structure that covers the tip of the root.$\newline$ - It does not give rise to root hairs.$\newline \bullet$Region of Meristematic Activity:$\newline$ - This region contains actively dividing cells that contribute to root growth.$\newline$ - Root hairs do not develop directly from this region.$\newline \bullet$Region of Maturation:$\newline$ - This is the area where cells differentiate and mature.$\newline$ - Root hairs develop from this region as cells differentiate into specialized structures.$\newline$Therefore, the correct answer is that root hairs develop from the region of maturation.$\newline$This corresponds to Option 4.
