Final Answer :
C
Explanation :
The notochord is a dorsal supporting rod present in the early embryonic development of the vertebrates. The neural plate is the precursor to the neural tube, which eventually becomes the spinal cord and brain. The neurula is a stage of development in some organisms, and the vertebral column forms later in embryonic development as the notochord is replaced.
