Explanation:
When analyzing the given options, it is important to understand the legal concepts involved in contract law. A contract is a legally binding agreement between two or more parties. For a contract to be valid, it must meet certain requirements, including free consent, lawful object, and consideration.
In this case, the agreement is said to have been entered into with free consent, which means that the parties involved willingly and voluntarily agreed to the terms of the contract. Additionally, the agreement has a lawful object, which means that it is not against the law or public policy.
However, the consideration mentioned in the agreement is inadequate. Consideration refers to something of value that is given in exchange for the promises made in the contract. It is an essential element of a valid contract.
Considering these factors, the correct answer is:
Answer: D. Valid
The agreement is valid because it fulfills the requirements of free consent and lawful object. The inadequacy of consideration does not render the agreement void or voidable. In contract law, the court does not usually assess the adequacy of consideration, as long as some consideration is present.
To summarize:
- The agreement is entered into with free consent and has a lawful object.
- The consideration mentioned in the agreement is inadequate.
- Despite the inadequacy of consideration, the agreement is still considered valid.
- The agreement is not void, voidable, or illegal.
- In contract law, the court does not usually assess the adequacy of consideration.
Note: It is always important to consult with a legal professional for specific advice regarding contract law in your jurisdiction.
