Final answer:
Carrie's garden extending onto Amanda's property is known as an encroachment, which is a physical violation of Amanda's property rights.The correct answer is option D.
Step-by-step explanation:
When Carrie's garden extends onto Amanda's property without Amanda's permission, this situation is known as D) An encroachment.
An encroachment is a situation where a property owner violates the property rights of their neighbor by building on or extending their own property into the neighbor's land without permission.
This differs from an easement by prescription, which is the right to use the property of another after a certain period of usage, and a license, which is a temporary permission.
A nuisance, on the other hand, would be an interference with Amanda's enjoyment of her property, which could be the case here as well but is not specific to the unauthorized physical extension of Carrie's garden.The correct answer is option D.
