For an Item of Evidence to Be Authenticated Using the Chain

For an item of evidence to be authenticated using the chain of custody theory:

A) the prosecution must generally account for the location and control of the item from the time it was secured at a crime scene until it is introduced in court as evidence.
B) even minor gaps in the chain of custody will virtually always result in the item of evidence being excluded from the criminal trial.
C) the item of evidence must have a serial number introduced in court that will demonstrate that the item of evidence is the same one found at the crime scene.
D) must be proof that the evidence never left the police property room for any reason until the day of trial, when the item of evidence was introduced.
