The correct answer is B. Slow or stop efficient fat elimination and metabolism. Dehydration can negatively impact metabolism and fat elimination processes in the body. It can also lead to cases of diarrhea (option C), but it does not directly affect brain functions (option A) or cause the skin to take on a soft supple texture (option D).
