A. In examining a witness concerning a prior statement made by the witness whether in a record or not, the statement need not be shown nor its contents disclosed to the witness at that time but on request the same shall be shown or disclosed to opposing counsel just prior to the cross-examination of the witness.

B. Extrinsic evidence of a prior inconsistent statement by a witness is not admissible unless the witness is afforded an opportunity to explain or deny the same and the opposite party is afforded an opportunity to interrogate the witness thereon. This provision does not apply to admissions of a party opponent as defined in paragraph 2 of subsection B of Section 2801 of this title.
