Answer:
B. $84,000
Explanation:
The computation of the income tax expense is shown below:
Income before income tax $300,000
Less: Permanent difference -$20,000
Taxable income $280,000
Tax rate is 30%
Income tax expense $84,000 ($280,000 × 30%)
The $50,000 do not impact the overall income tax expense but it decrease the amount of income tax payable
