Final answer:
The correct statement is A) If the post-box rule does apply, there is a binding contract. This is because under the post-box rule, the acceptance is effective when sent, which in this case occurred before the revocation was received.
Step-by-step explanation:
The scenario presented revolves around the post-box rule, which is a principle in contract law that determines the moment at which an offer is considered accepted. Typically, the rule states that an acceptance of an offer becomes effective when it is posted, not when it is received by the offeror. In this instance, Jones sends a letter attempting to renegotiate the price for Smith's florist services, followed by a letter of revocation, while Smith sends a letter of acceptance after the first letter but before he could reasonably have received the letter of revocation.
Under the post-box rule, if it applies, then there is a binding contract as soon as Smith posted his acceptance on January 15, which happened before he could have received Jones's revocation. Therefore, the correct statement is:
A) If the post-box rule does apply, there is a binding contract.
However, it is important to consider that if the post-box rule does not apply, and acceptances are only effective upon receipt, then the revocation would take precedence since it was sent before Smith posted his acceptance, making there no contract.
