The notochord is indeed derived from the mesoderm. The mesoderm is the middle germ layer in the early embryo that also gives rise to muscles, bones, and the circulatory system. The other options are incorrect because hair follicles are derived from the ectoderm, the liver is derived from the endoderm, and the lungs have components derived from both the endoderm (for the epithelial linings) and the mesoderm (for the connective tissues, blood vessels, and smooth muscles).
