Is the answer D?

A landowner's best friend had just found a new job and needed to find a new place to live. The landowner's property was ideally located near the best friend's new place of employment. The landowner agreed in writing to allow his friend to live on the property as long as the friend promised to maintain the property. The friend immediately began living on and maintaining the property. Several months later, the landowner decided to sell the property to his neighbor, who intended to live on it. Prior to completion of the sale, the neighbor inspected the property, and saw that the landowner's friend lived there. After the sale was complete, the neighbor asked the landowner's friend to vacate the property immediately, but the friend refused. He has been maintaining the property in good condition since he moved onto it. The jurisdiction in question applies the common law. Will the neighbor prevail in an action to take possession of the property and force the landowner's friend to vacate?

(A) Yes, because the landowner terminated the tenancy. (B) No, because the neighbor had notice of the friend's occupancy of the property prior to completing his purchase of the property. (C) No, because the friend has properly maintained the property. (D) No, because the neighbor is required to give the friend one period's notice.
