Wait, does this mean I can't use my 'Bring Your Own Conduit' policy at work anymore? Darn it, I was really looking forward to that.

Hmm, this one's a bit tricky. I was about to go with B, but then I remembered that the question specifically mentions 'EMI exceeding 5 kVA', so the metal conduit is probably necessary. C it is!

I think C is the correct answer because both cables need to be enclosed in a grounded metal conduit pathway.

Is this a trick question? I would have gone with A, since the telecom cables are already shielded in a metal conduit, so the power cables don't need to be shielded too. But I guess C is the right answer.

I think the correct answer is C. Enclosing both power and telecom cables in grounded metal conduits provides the necessary shielding to meet the minimum separation distance requirement.
