Step-by-Step Solution

Let's simplify this expression while following the order of operations which states that exponents come before multiplication and division, which come before addition and subtraction, and that parentheses come before all of them,

therefore we'll start by simplifying the expression in parentheses, since multiplication comes before addition and subtraction, we'll first perform the multiplications in this expression and then the addition and subtraction operations in the expression, in the next step we'll perform the subtraction operation that applies to the expression in parentheses and finish simplifying the expression:

17(3542+23)=17(158+6)=1713=4 17-(3\cdot5-4\cdot2+2\cdot3)= \\ 17-(15-8+6)= \\ 17-13=\\ 4 Therefore the correct answer is answer C.
