Richard, who is cleaning out his garage, offers to sell Dawn a used computer for $$200.$ Dawn replies that "I'll think about it and buy it if I decide to do so$."$ Richard also calls Denise and offers to give Denise a used business law book for $$50.$ She asks if she can clean his apartment instead, and he agrees. Richard also agrees to sell a communications book for $$5$ to Jill who also promises to pick it up the next day. Meanwhile, Sam comes to visit, offers Richard $$45$ for the business law book; and Richard sells it to him because he decides his apartment is clean enough. Sam also offers Richard $$50$ for the used computer. Richard sells it to Sam because he does not expect to hear from Dawn. Sam sees the communications book and offers Richard $$45$ for it$.$ Richard decides to forget about Jill and proceeds to sell the book to Sam for $$45.$ The next day Denise shows up to clean Richard's apartment and is very angry because Richard did not save the book for her. Denise claims that Richard breached their contract because they had a deal. Richard says that they never had a deal because no consideration was present and that even if cleaning house would be considered consideration, it would have been wholly inadequate to support receipt of the book. Jill is also angry because Richard sold the communications book and informs him that he breached the contract he had with her. Richard tells her that he had no obligation to hold the book for her because they had a unilateral contract. Two days after they first talked, Dawn tells Richard that she would like the computer. She tells him that her response bound him and that he should have awaited her action. Richard tells Sam that he needs to return everything for a full refund. Sam refuses. Which of the following is true regarding Richard's claim regarding the inadequacy of house cleaning as consideration?

Richard is correct because cleaning house would not constitute a benefit to the promisor.

Richard is correct because cleaning house would not constitute a detriment to the promise.

Richard is correct because Denise had only promised $-$ she had not actually performed.

Richard is incorrect because housecleaning would constitute consideration that would support a contract, and the court would not likely be concerned with the fact that the cleaning duties would be light.
