Which of the following are essential elements of an offer in contract formation?

• A. Offers must be in writing and communicated personally; oral offers are never valid.
• B. Clear expression of willingness to enter into a contract; terms sufficiently definite; not merely an invitation to treat.
• C. An invitation to treat is always the same as an offer.
• D. Consideration is required for the formation of an offer.

Answer: (B)

The concept being tested is what makes a statement an offer capable of creating a contract. The best answer rests on three elements: first, a clear expression of willingness to enter into a contract on specific terms; second, those terms must be sufficiently definite so that, once accepted, a binding agreement is created without needing further negotiations; and third, the statement should not be merely an invitation to treat, which is an invitation for others to make offers rather than a binding promise to be bound upon acceptance.

If someone says, for example, “I will sell you my car for £5,000,” that expresses a definite offer — it shows an intention to be bound if the other person accepts and the essential terms (what is being sold, the price) are clear. On the other hand, stating “Prices start at £5,000” or displaying items in a shop is generally an invitation to treat: it invites customers to make offers, which the seller can accept or reject. An offer can be made in writing or spoken, and it does not require consideration to be identified at the moment of making the offer; consideration comes into play when forming a binding contract, but it isn’t what defines an offer itself.

So the correct statement captures that the essential elements are a clear willingness to enter into a contract, definite terms, and not merely an invitation to treat, which is why it’s the best answer.
