What are the functions and components of the mucosa's individual layers?

All the structures of the alimentary canal have 4 similar major histological tissues . Which of the following descriptions of the tissue layers contains innacurate information? A) The mucosa layer consits of a simple epithelium (responsible for absoprtion), a lamina proprioa (supports the epithelium) and muscularis mucosae (thats ivolved with peristalsis.  B) The muscularis externa has 2 or 3 layers of smooth msulce and is involced with persistalsis  C) The submucosa layer is a connective tissue layer that anchors the mucosa layer and contains many blood vessels, lyphatic vessels, and nerves D) The serosa layer is a connective tissue layer that tethers the alimnetary canal to the appropirate body cavitities.  I believe that D is false but I am not certain
