Not sure on the rope but was taught at A&P school "Don't touch the cable until it's been able to touch the ground" due to static electricity. Never had a chance or was inclined to test that one out. So what's the correct answer with no wind?
Depends on how much fiber is in your diet.
I say A, assuming wind resistance is negligible. The cable is effected by several forces, gravity, momentum and acceleration. We are supposed to assume the helicopter has been flying for a period of time. The entirety of the cable should be moving without wind resistance at the same rate of speed as the helicopter assuming only gravity and acceleration remain constant, w/o aerodynamic load.
Speed very slow C, top part of the rope in rotorwash up close would get pushed down and graviy would be a factor. Higher speed B, just hanging on along for the ride in the breeze..
Weight of the cable itself should add to the "straightness" (rigidity?) of the upper part. The lower part is carrying less weight and would be more likely to drag back in the "wind" created by forward motion (figure C).

A), with wind negligible, like in a hover?
There is wind resistance.
I agree, but from the wording I am using a strict interpretation. I agree, there would will be some wind, some wind resistance some aerodynamic load... For those who fly I am an amateur physicist, not an aeronautical engineer! Even worse I only spent the night once in a Holiday Inn Express, and that was a few years ago...
BTW, excellent mental exercise, need more coffee and cowbell.
