Which of the following is NOT considered a tort to realty?

Conversion of property refers to an unlawful exercise of dominion over the personal property of another, typically involving physical possession and use. It pertains specifically to personal property rights rather than real property, which includes land and anything permanently attached to it, like buildings.

In contrast, trespass is the unauthorized entry onto another person's real property, which explicitly harms the rights of the property owner. Nuisance involves actions that interfere with the use and enjoyment of real property, impacting neighbors or the surrounding environment in negative ways. Adverse possession involves a person claiming rights to land through continuous and open possession over a period of time, which directly relates to realty as it concerns ownership claims.

Thus, conversion is not recognized as a tort to realty, making it the correct choice in distinguishing it from trespass, nuisance, and adverse possession, all of which directly involve rights and harms related to real property.
