An Executed Consideration is an act done in response to a positive promise. Let's break down the answer and explain it in detail.

Definition of Executed Consideration
Consideration is a fundamental principle in contract law. It refers to something of value that is given by one party to another in exchange for a promise or performance. Executed consideration, specifically, refers to an act that has already been performed in response to a promise. In other words, it is an act that has been completed or executed.

Explanation of the Correct Answer
The correct answer is option 'C', which states that an Executed Consideration is an act done in response to a positive promise. Here's an explanation of why this answer is correct:

1. An Act Done
Executed consideration involves an actual act or performance rather than a promise. It means that one party has already completed their part of the contract by performing an act.

2. In Response to a Positive Promise
The act done in executed consideration is in response to a positive promise made by the other party. A positive promise refers to a clear and definite commitment to do something in the future. The act is done with the expectation that the promise will be fulfilled.

Examples of Executed Consideration
To better understand executed consideration, let's consider a few examples:

1. A promises to pay B $500 if B paints A's house. B completes the painting, and A is legally obligated to pay the agreed amount. Here, B's act of painting the house is the executed consideration.

2. X promises to give Y a laptop if Y helps X organize a charity event. Y successfully organizes the event, and X is now obligated to provide the laptop. Y's act of organizing the charity event is the executed consideration.

Conclusion
In conclusion, an executed consideration is an act done in response to a positive promise. It involves the completion of an act with the expectation that the promise will be fulfilled. This concept is important in contract law as it ensures that both parties have fulfilled their obligations and can enforce the terms of the contract.
