What Is the Most Likely Explanation for the Impaired Functioning

What is the most likely explanation for the impaired functioning of the GI tract resulting from folate deficiency?

A) Since folate is required for bile synthesis, folate deficiency results in insufficient bile production, thereby promoting fat malabsorption and diarrhea
B) Since folate functions, in large part, in the process of cell renewal, a deficiency slows mucosal cell replacement, thereby resulting in decreased GI functioning
C) The anemia of folate deficiency results in decreased oxygen supply to body tissues, with the intestines being particularly affected because of their high metabolic activity
D) Since folate functions, in part, in the synthesis of pancreatic digestive enzymes, a deficiency leads to decreased enzymatic capacity in the intestines, thereby resulting in malabsorption
