Answer: B- A library card
Step-by-step explanation:
A legal document can be defined as a document which establishes an identity of a person, establishes right on the property, spouse, and any other entity. A legal documents are also signed to show the contractual treaty or deal.
A U.S. passport, a birth certificate, and a social security card all establishes identity of a person and are subjected to be presented in judicial matters when required. The library card also establishes the identity but is not as reliable for judicial proceedings as other documents are.
