Best answer
Right choice is (c) protoderm

Easy explanation: The octants (eight embryonic) cells divide periclinally (type of cell division that occurs parallel to the cells) to produce a dermatogen or an outer layer of protoderm. The inner cells differentiate into ground meristem (periblem) and procambium (plerome).
