You keep repeating the same question, which I answered for you, and which does not make sense.
As Reiny pointed out, the rings and chirps will occur at the same time every 6 seconds, or at
6, 12, 18, 24, 30, 36,.... seconds.
So which of the 4 choices will be a moment where the two sounds will occur together?
