Wait, are we sure 305 mm is enough? Seems risky.

C sounds right to me. Both need to be grounded.

Definitely B! Non-metal conduit won't help much.

I think it's option A. Grounded metal conduit makes a difference.

I’m a bit confused about the specifics, but I recall that unshielded cables are more susceptible to EMI, so maybe A or B could be risky?

I practiced a similar question, and I think C might be the right choice since both cables are in grounded conduits, which should minimize interference.

I'm not entirely sure, but I feel like non-metal conduits wouldn't provide enough protection, so B seems less likely.

I think I remember that grounded metal conduits can help reduce EMI, so maybe option A is correct?

I'm a little confused by the wording of the options. I'll need to think this through more carefully before selecting an answer.

Okay, I remember learning about portlets in class. I think I know the right answer, but I'll double-check the details just to be sure.
