B Correct answer
Explanation

The liver develops from the endodermal germ layer during embryogenesis, arising as an outpouching of the foregut. This endodermal origin is consistent with the digestive tract and its accessory organs. Ectoderm forms skin and nervous tissue, while mesoderm forms muscle, bone, and connective tissue.
