Writing the number in scientific notation means moving the decimal point to create a number between 1 and 10, and multiplying by a power of 10. In this case, moving the decimal point to the left gives 1.86, which is between 1 and 10. Multiplying by 10^5 gives 186,000, which is the answer in choice A.
