Hal Divelbiss Owned a Corner Lot Located Next to an Elementary

Hal Divelbiss owned a corner lot located next to an elementary school. Children from the neighborhood cut across the lot diagonally as they were walking to school. The children did so with such frequency that there was a visible path across Hal's property. The children had been using the path since the school opened in 1971. On December 1, 2000, Hal placed a fence around the perimeter of the lot and the children could no longer use their well-established short cut. Hal:

A) Could be liable for injuries to the children that they experience while using the path.
B) Would not be liable to the children for any injuries because they are trespassers.
C) Would be liable only for attractive nuisances.
D) Could utilize man traps without liability because the children are trespassers.
