If you must enter a crime scene to render live saving aid, do not - anything.

• A. Move anything
• B. Touch anything
• C. Disturb anything
• D. Read anything

Answer: (B)

Preserving evidence at a crime scene while giving emergency aid is the key idea. Touching items at the scene can transfer materials, alter positions, or leave trace evidence behind, which can compromise the investigation. Therefore, the best approach is to refrain from handling anything at the scene. You can still provide life-saving care to the victim and call for investigators, but avoid interacting with the environment or objects unless absolutely necessary and coordinated with responders. The other options imply touching or moving items, which increases the risk of contaminating or altering evidence and is less appropriate.
