The answer is ECTODERM.
Explanation:
An early embryo (namely gastrula) develops three germ layers:
endoderm, mesoderm and ectoderm.
Ectoderm gives rise to neural tissues, skin and skin derivatives like hair and nails.
Mesoderm forms all connective tissues, like bones, muscles, etc and organs like kidneys.
Endoderm differentiates in lungs, alimentary canal and associated organs like liver.
