The question appears to have some sort of typographical error, and the given options do not seem to fit a typical multiplication problem involving the numbers 104 and 102. However, considering the provided options, '10-2' (provided as option D) seems to resemble a subtraction operation and makes more logical sense as something derived from the question format given. The item '10-2' simplifies to 8, which seems relevant despite the question's ambiguity.
