Zone 1 corresponds to which surface?

Explanation:
Zone 1 is mapped to the distal facial surface. The two-letter surface label DF stands for distal (toward the back) and facial (toward the cheek), which exactly matches the zone 1 designation in PSR surface zoning. The other options describe different surfaces (F is facial only, DL is distal-lingual, MF is mesial-facial) and don't correspond to zone 1.
