Answer:
D) $150,000
Explanation:
Insurance proceeds that are not reinvested in replacing damaged property are taxed. Apparently Prime corporation didn't reinvest into replacing the property, so this transaction should be taxed as a property sale. Prime received $400,000 for the building with a $350,000 basis which results in a net gain = $50,000.
The other $100,000 were given as replacement income and therefore should be taxed as such.
So the total taxable amount = $50,000 + $100,000 = $150,000
