The written form of the number 98 is "ninety-eight."

To determine the correct written form, you should follow these guidelines:

1. Write out the tens digit, which in this case is 90.
2. Insert a hyphen ("-") between the tens and ones digits to separate them.
3. Write out the ones digit, which in this case is 8.

Therefore, the correct written form is "ninety-eight," which means option B is the correct answer.
