im confused between B and C

I vote for C.

To determine the correct answer, let's analyze the options provided:

A. Refrigerate evidence to preserve it: Although refrigerating evidence may be necessary in certain circumstances, it is not a general rule to follow in every investigation. The preservation methods for evidence vary depending on the type of evidence and the case.

B. Call for a second investigator to help out: While collaboration and assistance from other investigators can be beneficial in many situations, it may not be the most crucial step to preserve evidence. It is important to remember that the question emphasizes the preservation of evidence.

C. Strive to involve evidence specialists at the earliest time: This option emphasizes the importance of involving evidence specialists as early as possible. Evidence specialists have expertise in preserving, documenting, and analyzing evidence, which can significantly contribute to a complete investigation. Involving them early ensures that evidence is properly handled and not compromised.

D. Call to update his or her boss and ask what to do next: While keeping supervisors informed is a good practice, involving them immediately to determine the next steps may not directly address the issue of preserving evidence.

Considering all these points, the correct answer would be C. Strive to involve evidence specialists at the earliest time. This option aligns with the principle of preserving evidence and ensuring a complete investigation by engaging professionals with expertise in evidence handling.
