Concept:
Chain of custody refers to the process of maintaining and documenting the handling of evidence from the time it is collected until it is presented in court. It ensures the integrity and reliability of evidence.
Step 1: Understanding chain of custody.
It is a legal and procedural concept that ensures that evidence has not been tampered with or altered during investigation.
Step 2: Identifying key elements.
The two essential elements are:
• Traceability – The ability to track the evidence at every stage.
• Continuity – Ensuring there are no gaps in the handling of evidence.
Step 3: Evaluating options.
• Option (A): Includes forensic analysis, which is not a fundamental element.
• Option (B): Not the core defining elements.
• Option (C): Correct, includes both traceability and continuity.
• Option (D): These are investigative practices, not core elements.
Step 4: Importance of these elements.
Without traceability and continuity, evidence can be challenged in court, reducing its admissibility.
Final Conclusion:
Thus, the correct answer is traceability and continuity.
