A) Protoxylem lies toward the outside and metaxylem lies inward
B) Metaxylem lies toward the outside and protoxylem lies inward
C) Metaxylem lies toward the lateral side and protoxylem lies inward
D) Protoxylem lies toward the lateral side and metaxylem lies inward
Explanation
Exarch It is the condition of vascular bundles in which the protoxylem
(earlier formed xylem) lies toward the outside and metaxylem (later formed xylem) lies toward inward Endarch It is the condition of vascular bundles in which the protoxylem (earlier formed xylem) lies toward the inner side and metaxylem (later formed xylem) lies outside
