Warren Company has taken a position in its tax return to claim a tax credit of $30 million (direct reduction in taxes payable) and has determined that its sustainability is "more likely than not," based on its technical merits. The tax credit would be a direct reduction in current taxes payable. Warren believes the likelihood that a $30 million, $18 million, or $6 million tax benefit will be sustained is 25%, 30%, and 45%, respectively. Warren's taxable income is $255 million for the year. Its effective tax rate is 40%. Warren's income tax expense for the year is?

A) $12 million.

B) $72 million.

C) $84 million.

D) $102 million.

Please provide details if possible, especially on the tax benefit probabilities. Thank you
