Seller offers to sell Buyer her antique record player for $80. Buyer replies, "Wouldn't you consider taking $50?" Seller says no. Buyer then says "OK, I'll take the record player for $80." No further communication existed between the parties. Has Buyer effectively and enforceably accepted Seller's offer?
(A) Yes, because Buyer's response to the $80 offer never terminated his power of acceptance.
(B) Yes, even though the power of acceptance briefly terminated when Buyer offered $50, Buyer then immediately accepted the original offer.
(C) No, because Buyer had only a power, and not a right, to accept.
(D) No, because Buyer made a counteroffer, which terminated the power of acceptance.
