Concept:
This question tests the understanding of fundamental legal and forensic terminologies used in criminal investigations. Each term has a precise definition and application in forensic science and law.
Step 1: Understanding Chain of Custody (A).
Chain of custody refers to the complete record or log that tracks the handling of evidence from the crime scene to the courtroom. It ensures integrity and admissibility of evidence.
Thus, A $\rightarrow$ IV.
Step 2: Understanding Corpus Delicti (B).
Corpus delicti means “body of the crime.” It refers to the principle that there must be proof that a crime has actually occurred before a person can be convicted.
Thus, B $\rightarrow$ III.
Step 3: Understanding Modus Operandi (C).
Modus operandi (MO) refers to the method or pattern of behavior used by a criminal while committing a crime. It helps in identifying suspects and linking crimes.
Thus, C $\rightarrow$ I.
Step 4: Understanding Probative (D).
Probative evidence is evidence that has the ability to prove or disprove something relevant in a case. It directly contributes to establishing facts.
Thus, D $\rightarrow$ II.
Step 5: Forming the correct combination.
\[
A-IV,\quad B-III,\quad C-I,\quad D-II
\]
Final Conclusion:
Hence, the correct option is (1).
