Neurulation is the development of the nervous system from the
a) mesoderm.
b) hypoderm.
c) ectoderm.
d) endoderm.

The correct option is: C) ectoderm

Explanation:

In the embryos of vertebrates, neurulation is a folding process by which neural plate transforms into neural tube. In this process, the notochord signals the ectoderm germ layer to form a neutral plate, which folds in upon itself and leads to the formation of a neural tube. This neural tube then differentiates into brain and the spinal cord, thus forming the central nervous system.
