The Left PACK supplies air to which areas, validating the description of the air distribution system?

Explanation:
Air distribution in many aircraft uses separate packs to condition and deliver air to different zones. The Left PACK is responsible for feeding both the cockpit and the left-hand cabin, so pilots and passengers in that forward-left area receive conditioned air from the same source. This arrangement is why the left pack’s output routes to the cockpit and the LH cabin rather than just one of those areas or the other side. The right cabin is served by the Right PACK, not the left, which is why options that point to only the cockpit, only the LH cabin, or the right cabin don’t fit.
