To express the number in scientific notation, we write it as a number between 1 and 10 multiplied by a power of 10. In this case, we can move the decimal point six places to the right to get 4.3, and since we moved the decimal point to the right, we need to multiply by a negative power of 10. The power is equal to the number of places we moved the decimal point, which in this case is 6, so the answer is 4.3 × 10^-6 m, or choice B.
