B Correct answer
Explanation

This is a numeral manipulation puzzle. The equation 101 - 102 = 1 is currently incorrect (it equals -1). Moving the numeral '2' upward transforms it into an exponent: 101 - 10² = 1, which is mathematically correct (101 - 100 = 1). This is a creative lateral thinking puzzle that requires visualizing how to rearrange numerals rather than standard arithmetic operations.
