If K audition is immediately before Y - KY, K cannot be #5 because T must follow K and in this scenario, Y would take the only available slot after K. K cannot be #2 because W must take place earlier than K and Z must take place earlier than Y but if K is second, there is only one slot - #1 for either W or Z, there is not enough space for both of them, hence we can conclude that K cannot be #2 (A).

If Z is #2 instead (E), we could come up with a valid scenario:
