In a Court of Law, Attorney A, the Attorney for Sun

In a court of law, Attorney A, the attorney for Sun City Hospital, introduces the medical record from the hospital as evidence. However, Attorney B, the attorney for the defendant, objects on the grounds that the medical record is subject to the hearsay rule which prohibits its admission as evidence. Attorney B's objection is overridden. Why?

A) The medical record does not belong to the hospital; therefore, the hospital has no right to release the medical record as evidence.
B) It would violate physician-patient privilege, even though the patient signed a proper release of information form.
C) The doctrine of res ipsa loquitur prevails; therefore, reference to the medical record is moot.
D) The medical record may be admitted as business records or as an explicit exception to hearsay rule.
