• A. Neural cell
• B. Notochordal cells
• C. Neural plate cells
• D. Neural crest cells

Answer 1

The correct option is D Neural crest cells

The ganglia of sympathetic and the central nervous system in frog develop from the neural crest cells. The neural crest also gives rise to CNS (i.e., brain and spinal cord) and PNS (Peripheral Nervous System). Neural crest cells are a temporary group of cells unique to vertebrates that arise from the embryonic ectoderm cell layer, and in turn give rise to a diverse cell lineage—including melanocytes, craniofacial cartilage and bone, smooth muscle, peripheral and enteric neurones and glia.sists of a pair of optic lobes. Optic lobes are involved in the frog's vision.
