Answer: C) A debit of $200,000.
Explanation:
In 2018, Hawk sold all the Diamond Investment bonds at $700.
The amount of reclassification adjustment would be;
= Sales price - original purchase price
= (1,000 * 700) - (1,000 * 500)
= $200,000
The amount should be debited to reverse the gains recorded over the other years.
