Answer:
C) $4,000.
Step-by-step explanation:
Sweet Sarah's basis should be the stock price at the moment that she decided to exercise her stock options. In this case Sarah decided to exercise her options when the stock was worth $20 each, therefore her basis would be = 10 NQO x 20 shares per NQO x $20 per share = $4,000.
Sarah's taxable gain = ($22 x 200) - $4,000 = $400
