Ted frequently visited Janet, his next-door neighbor. Janet was separated from her husband, Howard. Howard resided with his mother but jointly owned the house in which Janet resided. Late one night, Ted and Janet were sitting on the bed in Janet's bedroom drinking when Howard burst through the door and told Ted, "Get out." When Ted refused, Howard challenged him to go outside and "fight it out." Ted again refused. Howard then pulled a knife from his pocket and lunged at Ted. Ted grabbed a lamp, struck Howard on the head, and killed him. Ted is charged with murder.

On a charge of murder, Ted should be found:

A. Not guilty, because Ted had as much right as Howard to be in the house.
B. Not guilty, because Howard attacked Ted with a deadly weapon.
C. Guilty, because Ted's presence in Janet's bedroom prompted Howard's attack.
D. Guilty, because Ted's failure to obey Howard's order to leave the house made him a trespasser.
