A general contractor was planning to bid on a government project to build a bridge. The general contractor solicited bids from subcontractors for a variety of jobs including dredging work. The general contractor informed all of the subcontractors that their bids would be used for the general contractor's bid for the government bridge project. Among the bids for the dredging work, the lowest was $100,000, and the general contractor used this bid in making his overall bid to the government. The general contractor was awarded the government contract. Before the general contractor could contact anyone, the subcontractor who made the $100,000 bid called the general contractor to say that it was revoking its offer because it had made a mistake. The subcontractor was willing to do the work for $120,000. The general contractor refused and then found another subcontractor to do the dredging work for $110,000.
If the general contractor sues the subcontractor who initially bid $100,000 and wins a breach of contract lawsuit, it is probably because the court held:
(A) that the parties formed an express option contract to keep the subcontractor's $100,000 offer open for a reasonable time and the general contractor accepted within that time frame.
(B) that the subcontractor made an express offer for a unilateral contract where the beginning of performance was the general contractor's submission of his bid to the government.
(C) that an express conditional contract had formed where if the general contractor won the government bid, then the contract for dredging work would form.
(D) that the general contractor relied to its detriment on the subcontractors' bid.
