Final answer:
The correct statement is option C: Bush's order can be accepted only by Ajax's shipment of the goods ordered.
Step-by-step explanation:
The correct statement is option C: Bush's order can be accepted only by Ajax's shipment of the goods ordered. When Bush Hardware placed the order for 300 Ram hammers and Ajax accepted it in writing, a legally binding contract was formed.
However, by sending the 300 Strong hammers instead, Ajax did not fulfill the terms of the contract, and this constitutes a breach of contract. Ajax's note of accommodation does not cancel the contract, as it is not a valid counteroffer.
