Answer: (4) Statement I is incorrect but Statement II is true.
Explaination-
Endarch" refers to the condition where the xylem elements develop towards the center of the stem
“exarch” refers to the condition where the xylem elements develop towards the periphery of the stem.
These terms are not used to describe the position of secondary xylem, but rather the arrangement of primary xylem.
exarch condition is indeed more common in the root system, where the xylem elements develop outward from the center of the root.
