Answer: d. the consideration from Darla to Edward is the promise of $6,000 subject to a condition.
Explanation:
Based on the information given, we should note that if Edward agrees to Darla's offer, the consideration from Darla to Edward is the promise of $6,000 subject to a condition.
This is because Darla offered to pay Edward the $6,000 for his car, as long as she gets that much from her uncle's estate, which is under probation. In the case whereby she doesn't get up to $6000, then she won't be bake to buy the car for $6000.
