Vedclass · Answer

(A) The Assertion is true because the notochord is indeed a mesodermally derived,rod-like structure that develops on the dorsal side during the embryonic stage of all chordates.The Reason is also true because,in vertebrates,the notochord is replaced by a cartilaginous or bony vertebral column in the adult stage.Since the presence of the notochord (which is later replaced by the vertebral column) is a defining characteristic that distinguishes vertebrates from other chordates,the Reason correctly explains the nature and fate of the notochord in vertebrates.

Assertion: Notochord is a mesodermally derived rod-like structure formed on the dorsal side during embryonic development of chordates.
Reason: Notochord is replaced by the vertebral column in the adult vertebrate.
