This one is a classic :D
1) This is probably one of the "rare" instances where you would find Passive Voice is correct. So this could be the primary reason you could have fallen for the wrong answer. Passive Voice is a completely valid construction. We just don't use it as often as we use active voice.
2) The voice of thr wrong answer is a bit weird, this may have be one of the reason, you may have fallen for the wrong answer. They know students use this as a technique. So on harder questions, they can make it sound even weird.
Now KEEP CALM. Just Apply the rules.
The first part of the sentence is a noun modifier, it cannot modify the aviation officials. Here it means to the runway obvioulsy. Strike out A, E
We are left with C & D.
C introduces redundancy "during the time", so we strike out C.
Hence we are left with D. D sounds funny... but sounding funny is not an error. Each of the others has an actual error, so D is the only one left.
