Answer:
C Admissible, both as substantive evidence and for purposes of impeaching the doctor.
Step-by-step explanation:
The court should rule on the admissibility of the statement from the treatise as admissible, both as substantive evidence and for purposes of impeaching the doctor. A statement in Learned Treatises that are established as a reliable authority by the expert’s admission or testimony, by another expert’s testimony, or by judicial notice, are admissible evidence.
