Which statement is true about an encumbrance?

An encumbrance is a claim or liability that is attached to a property and affects the owner's ability to transfer ownership or affects the value of the property. Liens are one type of encumbrance, but there are other types such as easements, restrictions, and mortgages. Therefore, statement A is incorrect. Statement B is incorrect because encumbrances can reduce a property's value, such as with a mortgage or a restriction that limits the use of the property. Statement D is also incorrect because encumbrances do not transfer ownership, but they can limit or restrict it.
