Why is lymphatic tissue found all along the GI tract?

A) Different pathogens are activated at different points along the digestive tract, and the location of the lymphatic tissue allows the host to respond according to which pathogen is activating in that area. B) When an infection occurs, these lymphatic tissues are able to quickly stop digestion and the movement of the GI contents so that the infection doesn't spread throughout the body. C) Upon infection in a specific area of the GI tract, a response can quickly be delivered and flood the lumen of the GI tract in that region. D) When an infection occurs, these lymphatic tissues are able to quickly trigger an inflammatory response along the entire GI tract. E) Cells in these lymphatic tissues "sample" the environment by phagocytosis and present their findings to lymphocytes that may or may not need to initiate an immune response.
