Starting from the left, 3S1U1P1 means 3 times the digit in the millions place (0), 1 times the digit in the hundred thousands place (9), 1 times the digit in the ten thousands place (3), and 1 times the digit in the ones place (1), which equals 3(0) + 1(9) + 1(3) + 1(1) = 9.

Similarly, 9S1S1P0 means 9 times the digit in the millions place (2), 1 times the digit in the hundred thousands place (4), 1 times the digit in the ten thousands place (3), and 0 times the digit in the ones place, which equals 9(2) + 1(4) + 1(3) + 0(0) = 23.

So the expression simplifies to 9 - 23 = -14.

None of the answer choices match -14, so we must recheck our calculation. Starting from the right, -4S1S1P0 means -4 times the digit in the millions place (2), 1 times the digit in the hundred thousands place (4), 1 times the digit in the ten thousands place (3), and 0 times the digit in the ones place, which equals -4(2) + 1(4) + 1(3) + 0(0) = -5.

Now we have 9 - 5 = 4, which matches answer choice B.
