Adams Finds That It Takes Less Time to Get Home

Adams finds that it takes less time to get home when she walks through Benson's yard instead of going around it.She asks Benson's permission to cross his land, and Benson says, "All right, but you must stop walking across when I say so because I don't want my grass to die." By letting Adams walk across his property, Benson has created

A) an easement because it gives Adams the right to do an act on Benson's property.
B) a license because Benson may revoke the privilege at any time.
C) an estate because it is an interest in land.
D) None of the above is correct.
