Question 11

Performance obligations of the parties differentiate a bilateral contract from a unilateral contract.

In a bilateral contract, both parties exchange mutual promises and have performance obligations toward each other, whereas in a unilateral contract, only one party makes a promise contingent upon the performance of an act by the other party.

A) number of parties involved

This option is incorrect because both bilateral and unilateral contracts can involve two parties. The key difference lies not in the number of parties, but in the nature of the obligations each party has under the contract.

B) performance obligations of the parties

This option is correct as it highlights that a bilateral contract involves mutual obligations where both parties promise to perform certain duties, while a unilateral contract only requires one party to fulfill an obligation upon the completion of a specific act by the other party.

C) relative value of the object of the contract

This option is incorrect since the relative value of the object does not distinguish between bilateral and unilateral contracts. Both types of contracts can involve varying values, and this aspect does not affect their classification.

D) type of property specified in the contract

This option is incorrect as the type of property involved in the contract does not differentiate bilateral from unilateral contracts. Both types can pertain to tangible or intangible property, and this characteristic does not define the contract type.

Conclusion

The defining feature of bilateral contracts is the mutual performance obligations between parties, which distinguishes them from unilateral contracts where only one party is obligated to act. Therefore, option B accurately captures this distinction, while the other options fail to address the fundamental differences in obligations inherent to the contract types.
