Final answer:

Dr. Romano would instruct police officers to avoid cross-contamination by ensuring evidence is separated and individually contained to maintain its integrity for forensic analysis.

Step-by-step explanation:

Dr. Romano, in teaching police officers how to collect evidence at a crime scene, would most likely explain that cross-contamination must be avoided to preserve the integrity of the evidence. The correct approach he would suggest is to ensure that evidence should be separated so it doesn’t transfer properties to other objects. This involves using individual containers for each piece of evidence, thus preventing any mixing of materials or transfer of particles that could compromise the investigation or the validity of the forensic analysis later in the courtroom.
