Which of the following is false regarding the general rule that courts will not enforce illegal bargains?

If several considerations, one of which is bad, are given for several promises, and the legal consideration is by its terms apportioned to the legal promise, the legal part is enforceable.

If any part of the consideration that is given for a single promise is illegal and there is no possibility of separation, there can be no enforcement.

If the contract is executed, a court will permit rescission and recovery of what was given in performance.

If two promises, one lawful and one unlawful, are given for a legal consideration, the lawful promise is enforceable.
