Which scenario represents a terminable easement?

A terminable easement is one that has specific conditions or events that can lead to its termination. In the scenario where an easement ends when a fence is removed, there is a clear condition tied to the continuation of the easement. If the fence, which may serve as a defining feature of that easement, is removed, it directly impacts the easement's validity and results in its termination.

This highlights the nature of terminable easements, as they are not perpetual and are contingent upon certain actions or situations. In this case, the physical removal of the fence serves as a definitive endpoint for the easement, illustrating its terminable quality.

In contrast, the other scenarios either describe easements with indefinite duration or those reliant on contractual agreements, which do not meet the criteria of being terminable based on specific conditions. This distinction is essential in understanding how and why certain easements can be ended under particular circumstances.
