1.The "mirror image rule" states that:

a.The consideration being promised by both parties must be roughly equal in value and therefore the approximate mirror image of each other

b.in breach of contract lawsuit, the winning party should be allowed to recover the mirror image of what he or she was promised in the contract

c.an agreement is only a valid contract if someone accepts the mirror image that he or she was offered by the other party

d.a contract is unconscionable if a reasonable would not be able to look at their own mirror image without shame because of how unfair the contract is to the other party

I am confused which one is correct answer a, b, c or d?
