What describes an easement in which private property is taken for public use via eminent domain?

An easement by condemnation is specifically the legal process through which private property is taken for public use, typically through the government’s power of eminent domain. This process allows governmental entities to acquire private land to build infrastructure like roads, schools, or utilities, compensating the owner as required by law. In this context, "condemnation" refers to the act of legally appropriating property, which can happen even if the property owner does not wish to sell.

The other options outline different types of easements. A prescriptive easement arises when someone uses a portion of someone else's property without permission, leading to a right to continue that use after a certain period. A statutory easement is created by law for specific purposes, such as utility companies needing access to maintain services. An appurtenant easement benefits a particular piece of land and is attached to it, allowing the owner specific rights over a neighboring property.

In this case, the concept of taking property for public use points directly to the process defined as easement by condemnation, making it the correct answer.
