B)[(2 + 3) + (5 * 4)] * (6 - 1) 
C)2 + 3 + 5 * 4 - 6 - 1 
D)(2 + 3) * (5 * 4) * (6 - 1)

Starting from the bottom of the tree, we first evaluate the expression inside the parentheses: 2+3=5 and 5*4=20. Then we add 20 to the other expression inside the parentheses: 5+20=25. Finally, we multiply 25 by the result of 6-1=5: 25*5=125. This matches the arithmetic expression in choice B.
