Answer:
option D - $22,000 gain
Step-by-step explanation:
the gain can be calculated by using the following relation
Face Value + Unamortized Premium - Purchase Price = gain
where,
Face Value - $1,000,000
Unamortized Premium - 60% x $20,000
Purchase Price - 99% x $1,000,000
putting all value to get gain or loss on the retirement
= $1,000,000 + (60% x $20,000) - (99% x $1,000,000)
= $22,000 gain
