Step-by-step explanation:
A promise to refrain from doing something can indeed serve as consideration for a contract, which means that the correct answer to the question is A. True.
In legal terms, consideration is one of the main components required to constitute a contract. Consideration refers to something of value that is promised to another when making a contract. It can be an action, money, or even an agreement not to perform a certain action. When one party agrees to not do something they are legally entitled to do, this forebearance is considered a form of consideration because it demonstrates the party's agreement to give something up for the benefit of the contract.
