Carl and Ron Both Work in Road Construction

Carl and Ron both work in road construction. They know that two major jobs are going to be up for public bids, and agree between themselves that Carl will bid on one job and Ron will bid on the other, so that they both have work for the summer. When the bids are opened, Carl realizes that Ron has bid on both jobs. Ron is awarded both contracts. If Carl now wants to sue Ron for breach of contract:

A) Carl would probably win on the basis of promissory estoppel since he has detrimentally relied upon Ron's representation that he would not bid.
B) since Carl is less at fault than Ron, the court will likely award Carl damages.
C) the agreement will not be enforced by the courts because it violates public policy.
D) the agreement will not be enforced by the courts because it obstructs the administration of justice.
