Answer:
$4,800,000 credit
Step-by-step explanation:
Total Paid-in Capital after five years = 1,000,0000 * $8 = $8,000,0000
Paid-in Capital after 3 years = $8,000,0000 * (3 / 5) = $4,800,000
Therefore, the balance in "Paid-in Capital—Stock Options" three years after the grant date would be $4,800,000 credit.
