Answer: D

Explanation:

A contract must involve consideration to be valid.

For a contract to be valid, it must be for a legal purpose and involve consideration, which is the exchange of value between parties.

A) be offered.

While an offer is a crucial component of forming a contract, it alone does not ensure the contract's validity without consideration. An offer must be accepted and supported by consideration to create a binding agreement.

B) involve warranties.

Warranties may be included in contracts, but they are not a requirement for a contract's validity. The presence of warranties does not substitute the need for consideration, which is essential for creating enforceable obligations.

C) be written.

Contracts can be valid regardless of whether they are written or oral, as long as they satisfy the legal requirements, including the need for consideration. Therefore, the written form is not a strict requirement for validity.

D) involve consideration.

Consideration is a fundamental requirement for a contract's validity, as it refers to something of value exchanged between the parties. Without consideration, a contract lacks the necessary legal enforceability, making this option the correct answer.

Conclusion

In summary, a valid contract must not only be for a legal purpose but also involve consideration, which is essential for establishing mutual obligations. The other options, while relevant to contract formation and enforcement, do not fulfill the legal requirement necessary for a contract to be deemed valid.
