Which of the following proves or disproves a specific act through oral testimony based on
information gathered through the witness’s five senses?

A.
direct evidence

B.
best evidence

C.
conclusive evidence

D.
hearsay evidence

Explanation:
As stated in the CISSP documentation, “If you want to achieve the validation or revalidation of the
oral testimony of a witness, you need to provide physical, direct evidence to backup your statements

and override the five senses of an oral testimony”. Circumstantial or Corroborative evidence is not
enough in this case, we need direct, relevant evidence backing up the facts.
