Step-by-step explanation:
The correct answer to the question is B) Witness testimony.
Witness testimony is not subject to any statute of limitations and can be used in litigation even years or decades after the incident. This is because witness testimony is considered firsthand evidence of an event and can provide valuable information in a legal case.
For example, if there was a crime committed many years ago and a witness comes forward with information, their testimony can still be used to pursue legal action against the responsible party.
