The key idea is understanding how often smoke or gas inhalation injuries occur relative to other injury types. In this set, inhalation injuries account for about seven percent of firefighter injuries. That makes seven percent the best pick because it aligns with the given data or typical injury distributions where inhalation injuries are relatively less common than other causes.

A smaller figure, like five percent, would understate the share shown; a much larger figure, such as fifteen or forty-eight percent, would imply inhalation injuries are far more common than the data indicates, which isn’t supported by the distribution described.
