Grace offers to sell Misti her car for $$5,000.$ Grace tells Misti, $$If I don$$t hear from you in three days, I$$ll assume you$$re buying the car.$$ Four days go by and Grace has not heard from Misti. Does Misti$$s silence amount to acceptance?

Yes, because Misti failed to notify Grace of any rejection within three days.

No$,$ because an offeror cannot impose on the offeree a duty to respond to the offer.

Yes, because Misti did not reject to the term.

No$,$ because acceptance must be oral or written.
