D seems like the obvious choice here. If we're not using statistical methods, how can we possibly project the results back to the population? That's just common sense.
Wait, if non-statistical sampling doesn't require the sample to be representative, then how are we supposed to draw any meaningful conclusions about the population? Sounds like a recipe for disaster to me.
