In animal development, which of the following germ layers is correctly matched with a structure it typically gives rise to?

  • option_a: Ectoderm – Inner lining of the digestive tract
  • option_b: Mesoderm – Notochord
  • option_c: Endoderm – Neural tube
  • option_d: Mesoderm – Epidermis of the skin

Explanation

The text states: 'ectoderm blue , which forms the outer layer of the embryo, mesoderm red , which forms the middle layer, and endoderm yellow , which gives rise to the innermost tissues.' It further mentions that 'Early events in organogenesis in vertebrates include neurulation: formation of the notochord by cells of the dorsal mesoderm'. This directly matches mesoderm with notochord.
