Which line indicates NBC contamination?

Explanation:
NBC contamination shows up as a detectable spike in the reading on the detector, standing out from normal background levels. In the diagram, one line has a clear spike well above the others, while the rest stay near baseline. That elevated signal indicates the presence of NBC agents along that path, making that line the contaminated one. The other lines remain at background levels, so they don’t indicate contamination.
