In Considering the Competency of Evidence, Documentary Evidence

In considering the competency of evidence, documentary evidence:

A) is not subject to the restrictive rules respecting relevancy, materiality, and competency as is oral testimony, because it is unchanging evidence once it has been reduced to a writing.
B) must meet only the same rules regarding competency, relevancy, and materiality as testimonial evidence.
C) there is little dispute concerning competency because documents can be examined by all parties to the lawsuit.
D) is subject to the same rules respecting relevancy and materiality as is oral testimony and, in addition, documentary evidence must be authenticated in order to be considered competent evidence.
