Answer:
B) $300 loss
Explanation:
The seller of the call must sell the stock at $40. Since the seller received $7 per stock in order to write the call, his total revenue = $40 + $7 = $47 per stock. Since the stock's price is $50, the seller of the call will lose $3 per stock (= $50 - $47).
Since every call option includes 100 stocks, the total loss = $3 per stock x 100 stocks = $300 loss
