Jonas Smith Owns a Corner Lot That the School Children

Jonas Smith owns a corner lot that the school children use continually as a short cut on their way to and from Jackson Elementary. Smith grew tired of seeing the diagonal path. He posted signs, which did not deter the children. He erected a gate which they climbed over. He then posted an attack dog at 8:00 a.m. and 3:00 p.m. A child who tried to pet the dog was mauled.

A) Smith is liable for the child's injuries.
B) The child was a trespasser and Smith is not liable.
C) The child was a licensee, but was warned, hence Smith is not liable.
D) The child was an invitee.
