Answer:
A. Producer surplus
B. Neither
C. Consumer surplus
Explanation:
Producer surplus is the difference between the price of a good and the least amount the seller is willing to sell his product.
Producer surplus = price - least price the seller is willing to sell
$48 - $40 = $8
Consumer surplus is the difference between the willingness to pay of a consumer and the price of the good
Consumer surplus = willingness to pay - price of the good
$76 - $68 = $8
The second scenario doesn't indicate the willingness to pay of the consumer or the willingness to sell it the producer. So it is not about either consumer or producer surplus.
