The correct reason that ultraviolet light can be used to gather evidence of a crime is:
**Ultraviolet light causes substances to fluoresce and give off visible light.**
When certain materials or substances are exposed to ultraviolet light, they can absorb the UV radiation and then re-emit it as visible light, often in vibrant colors. This property is exploited in forensic investigations to detect things like bodily fluids, certain drugs, and other trace evidence that may not be visible under normal lighting conditions.
