Solution
The correct option is C Mesoderm
The primitive streak is a structure that forms in the blastula during early stages of avian, reptilian and mammalian embryonic development. When the early embryo consists of only two tissue layers, the ectoderm and the endoderm, a longitudinal thickening appears as a result of the multiplication of the ectodermal cells. This thickening called the primitive streak, gives rise to the notochord and the third basic layer called as the mesoderm.
Thus, the correct answer is option B, 'Mesoderm'.
