Answer:
Option C $450,000 decrease
Step-by-step explanation:
The reason is that the cost to buy the shares in the market is lower than $50 per share so buying the shares at $50 per share is not benefiting the directors at all. This means that the liability which was calculated using the black scholes model was standing at $1350,000 for 3 years and $450,000 for a single year will not be waived off because the directors didn't exercised the option and are taking money benefits which means under fair value method the net income will decrease by $450,000 because this is the amount paid to directors.
