Permissive use of a road across real property would cause a prescriptive easement in:

In the context of easements, permissive use refers to a situation where a property owner allows someone to use their property, such as a road, but this use does not establish a legal right to that use. A prescriptive easement, on the other hand, is typically acquired through continuous, open, and notorious use without the property owner's permission for a specific statutory period.

When the use of the road is permissive, it does not meet the criteria for establishing a prescriptive easement because the key element of "without permission" is missing. The user must demonstrate that their use was adverse or hostile to the property owner's interests, which is not the case when permission is granted—whether explicitly through a contract, verbally, or simply through a lack of objection.

Since permissive use does not lead to the establishment of a prescriptive easement, the correct answer highlights that none of the outlined scenarios, including those involving a legal contract, verbal permission, or lack of objection, would result in the creation of a prescriptive easement under the criteria established in property law.
