Which statement is INCORRECT for federally declared disaster area casualties?

The taxpayer does not recognize gain on proceeds for unscheduled property that was part of the contents of the home.

A taxpayer may choose to deduct the disaster area casualty loss on the tax return for the year before the year in which the disaster occurred.

The replacement period for a taxpayer's main home destroyed or damaged in a federal disaster area ends four years after the close of the first tax year in which any gain is realized.

The taxpayer has three years after the due date of the casualty-year tax return to file an amendment to claim a disaster area casualty for the preceding year.
