Final answer:
Bilateral contracts require mutual agreement between both parties, while unilateral contracts involve promises from both parties.
Step-by-step explanation:
Bilateral and unilateral contracts are best described by the following statements:
- D) Unilateral involves promises from both parties. A unilateral contract involves one party making a promise or offer that the other party can accept by performing a specific action. For example, if Party A promises to pay Party B $100 if Party B mows their lawn, Party B can accept the offer by mowing the lawn.
- A bilateral contract requires a mutual agreement between both parties involved. Both parties make promises to each other, and both parties are obligated to fulfill their promises. For example, if Party A promises to pay Party B $100, and Party B promises to provide a service in return, a bilateral contract is formed.
