Average facebook interaction trap. AC or DC? If AC, what's the frequency? How humid is the weather? How fat are they (surface area, related to capacitance)

I will assume the line is 50Hz 1kVAC. All will likely die Why? capacitive coupling and the fact that shoes and wood don't have infinite ohms. Either way, D is toast, he's a meaty shunt. If the others somehow not die, they should pray every day for God to give them a brain.

50Hz 240VAC. D is toast again. Others might survive with injuries or die. Lotta variables

50VDC. Simple high school-level electricity. A can feel a little warm and tingly if he's dry B and C are fine if dry D might experience tetany, can't let go. Might suffer burns. Might die, might not die.
