Haha, you know what they say, 'the devil is in the details!' This exam is really trying to test our attention to detail when it comes to cable separation requirements.

Hmm, good point. I think that could also work, but the question is specifically asking about the minimum separation distance, so the metal conduit for the telecom cables might give it a slight edge over option B.

But what about option A? If the power cables are unshielded and the telecommunication cables are enclosed in a grounded metal conduit, wouldn't that also provide adequate protection?

Okay, let's think this through. I'm leaning towards option C, where the power cables are unshielded and enclosed in a grounded metal conduit, while the telecommunication cables are also enclosed in a grounded metal conduit pathway. That seems to provide the best shielding and protection against EMI.

Yeah, I agree. The question seems a bit tricky, but I think the key is understanding the impact of shielding and conduit material on the required separation distance.

Hmm, this is an interesting question. I feel like they're really trying to test our knowledge on the proper separation distances between telecommunication and power cables, especially when dealing with EMI.
