If a part of goods has been delivered to the buyer and the third party fails to fix the prices, who shall pay a reasonable price?
The price in a contract of sale may be fixed by the contract, or it may be left to be fixed in manner thereby agreed or it can be determined by the course of dealing between the parties to the contract.
Where the priceis not determined in accordance with the said provisions, the buyer shall pay the seller a reasonable price. Reasonable price will depend on the individual case or circumstance.
Hence, B is the correct option.
