Answer:
b.The buyer will win since this is just a risk of doing business.
Step-by-step explanation:
In a general agreement or contract between a seller and the buyer both the parties are liable to perform some duties binding the contract.
In case any of the parties fail to perform such duties then that party is liable to make good to other party which did not default.
In the given case the buyer is in good health, it was because of the seller that the goods could not be delivered, and it was because of uncontrollable circumstances.
And that the seller is still liable because ultimately the goods could not be delivered.
Thus, the buyer shall stand to win the case against the seller.
