To determine the check digit for a USPS money order identification number, you need to perform a calculation using a special algorithm. First, add up all of the digits in the identification number (5+8+4+9+2+0+2+9+1+1=41), then take the remainder of this sum when divided by 9 (41 mod 9 = 5). The check digit is the difference between 9 and this remainder (9-5=4), which is 4. Therefore, the correct answer is B) 4.
