AI explanation
Standard operator precedence (as in PL/SQL and similar languages) evaluates, from highest to lowest: unary operators (unary minus/plus, negation) first, then multiplication and division, then addition, subtraction, and string concatenation (||) at the same lower level, evaluated left-to-right. This matches the three marked-correct rows exactly: unary +/- binds tightest, */÷ next, and +/-/|| last among these listed. 'None of these' is wrong because the three listed precedence levels are indeed the standard order.
