Option C all the way! Although, I have to admit, the thought of unshielded power cables and metal conduits makes me a little nervous. Wouldn't want to be the one testing that setup, if you know what I mean. *nervous laughter*

Hmm, this one's tricky. I'm leaning towards Option C, but I'd really like to know the reason behind the 305 mm (12 in) separation distance. Is it to prevent electromagnetic interference or just a safety thing? Inquiring minds want to know!

I'm going with Option C as well. It's the only one that mentions both power and telecommunication cables being enclosed in grounded metal conduits, which seems to be the key requirement.

Option C seems like the correct answer. The power cables are unshielded but enclosed in a grounded metal conduit, while the telecommunication cables are also enclosed in a grounded metal conduit. This should provide the required minimum separation distance.

I disagree, I believe the answer is C because both cables are enclosed in grounded metal conduits.
