Answer:
The chain of custody begins when the piece of evidence is brought to the crime lab.
Step-by-step explanation:
The chain of custody can be defined as a chronology of collecting evidence and the process of protecting the evidence thereafter. The chain of custody is a legal term used to define the documentation of any physical or electronic evidence from the crime scene.
The statement that is not true about the chain of custody from the given options is the second one. The statement is false that the chain of custody begins when evidence is presented in the crime lab rather the chain of custody begins when any piece of evidence is taken under custody, when it is collected by crime investigating officer from the crime scene. The moment any evidence is collected or taken under custody, the chain of custody of begins. Thus second statement from given options about the chain of custody is false.
