Answer:
Under these circumstances, the offer had not been communicated.
Explanation:
There are three characteristics an offer must have to be valid. The very first characteristic is being properly communicated by the offeror to the offeree in an intended manner. If the offeree finds out about the offer by chance and accepts it, it is invalid. That is precisely the case being described in the passage. Beck never communicated his offer to Sam. He was thinking of making an offer, and merely mentioned it to his mother. She was the one who conveyed the unintended message to Sam. Therefore, the offer has not been communicated by the offeror and is, for that reason, not valid.
