Contracts cannot be changed ____________.

Contracts cannot be changed ____________.

• A. Mutually
• B. Collaboratively
• C. Unilaterally
• D. After Consent

Answer: (C)

Contracts generally require both parties to agree before any term can be changed. A change by one party alone would alter obligations without the other party’s consent, which isn’t enforceable in ordinary circumstances. That’s why the best fill is unilaterally: it expresses that a contract cannot be changed by one side acting alone. Choices that imply changes can occur with mutual agreement or after some form of consent don’t fit the standard rule that modification needs mutual assent.
