There are choices for this question namely:
A. mesentery
B. small intestine
C. pharynx
D. large intestine
The correct answer is "mesentery". MALT or mucosa-associated lymphoid tissue is a collection of lymphoid tissue embedded in the mucosal layer of the gastrointestinal tract and other organs with mucosal linings. First of all, the mesentery has no mucosa; it is composed of connective tissues and fat tissue with blood vessels embedded in the mesentery. The other organs listed has MALT, most notably in the form of Peyer's patches in the small intestine (specifically, in the ileum).
