Why C is correct
Section 352.12(B) prohibits using PVC conduit to support luminaires. Trade size, fixture weight and Schedule 80 wall thickness do not create the claimed permissions. The limited conduit-body support permission in 352.10(I) is separate and does not allow those bodies to support luminaires.
