I think you need to go back and reread the question. As people have said on here a flying tail is a single item, like on the F4 Phantom (sorry it's the only one I know).
The answers are for an aircraft with a horizontal stabiliser with automatic stab trim etc, Like on the 747. Pilot pulls back the column elevator goes nose down, after a predetermined time (3secs off the top of my head) to off load the load to the pilot (and the structure) the stabiliser automatically trims nose down which reduces the elevator input (they fair as in answer C which is the correct answer) the a/c pitches up and the pilot can sit back and carry on drinking his coffee
If the A/P(s) is engaged and the pilot dials in a new altitude the initial reaction would be to move the elevators, again after a predetermined time the Auto Stab Trim will pick this up and trim out the elevator input by changing the stab position, again pilot goes back to drinking his coffee
Once the selected altitute is reached a similar thing happens to keep the a/c in straight and level flight (so the pilot doesn't spill his coffee
).
