If a deed provides for an easement granting ingress and egress over a neighboring property but fails to locate the easement, the:

Answer B (deed is voidable) is incorrect because voidability implies the deed can be affirmed or rescinded by one of the parties, which is not the appropriate legal framework for an easement with an unspecified location — the deed itself is valid, only the easement's location is uncertain.

Answer C is actually the most legally accurate statement under California law, as California courts have consistently held that when an easement location is unspecified, the servient tenement owner may designate a reasonable location — this answer should be carefully considered as potentially correct despite the question's stated answer of A.

Answer D (dominant tenement holder can choose any area) is incorrect because allowing the dominant owner to choose any area without restriction would give them an unreasonably broad right that could severely burden the servient property; California law favors the servient owner's right to designate a reasonable location.
