a. PVC
b. RMC
c. LFMC
d. FMC

Is this question in regards to the 2008 NEC?

If it is the only answer that might fit would be D, due to the change that does not allow FMC to be installed in wet locations. 225.22 requires raceways installed on the exterior of buildings to be arranged to drain and raintight where in a wet location.

The only problem is that ther are places on the exterior of a building that are not wet locations where FMC could be installed.
