See the answer below.

Work Step by Step

In the first two cases, the electron is removed from a bonding orbital, and in the last from an antibonding orbital. Since $B.O.=(N.\ Bonding -N.\ Antibonding)/2$ and that bond length decreases with bond order, the third case has a shorter bond because of the bigger bond order.
