Answer:
(B) Accept the low price happily
Step-by-step explanation:
As the customer was willing to pay up to 60 dollars for the item, the offer of 50 dollars will be acceptable as it is creating a consumer surplus of 10 dollars.
The customer will look for his own benefit and to his judgement, the deal is good as it saves 10 dollars.
The amount earn by the seller is irrelevant.
