Restrictive Covenants Impose Constraints on the Use of the Land

Restrictive covenants impose constraints on the use of the land, yet are limited in terms of their enforcement. All of the following are true regarding the enforcement of restrictive covenants EXCEPT:

A) Courts have been reluctant to maintain restrictive covenants for an unreasonably long time and in some cases states have enacted a time limit on their applicability.
B) Courts may refuse to enforce restrictive covenants due to changing neighborhood character.
C) Courts may refuse to enforce restrictive covenants due to abandonment of the property.
D) Restrictive covenants are public in nature and therefore can be enforced by those who do not hold a legal interest in the property.
