The correct answer is A.
An offer is a statement of willingness to enter into a contract. It must be clear, definite, and communicated to the offeree. Once an offer is accepted, it becomes a binding contract.
In this case, Mr. A’s advertisement is an offer to give a prize to the first person to swim the English channel and back during the month of August. F is the offeree. F accepts the offer by starting to swim on August 1st.
On August 2nd, Mr. A publishes a second advertisement stating that the offer has been withdrawn. However, this second advertisement is ineffective because it is not communicated to F. F is not aware of the withdrawal of the offer until after he has completed the swim.
Therefore, F can recover the prize.
Option B is incorrect because the offer was not revoked. An offer can be revoked if it is communicated to the offeree before acceptance. In this case, the second advertisement was not communicated to F until after he had accepted the offer.
Option C is incorrect because F cannot only claim for damages. F can recover the prize because he has accepted the offer and completed the swim.
Option D is incorrect because the answer is A.
