(a) For any species to have same bond order we can expect them to have same number of electrons. Calculating the number of electrons in various species.

O-2 (8 + 8 + 1 = 17); CN (6 + 7 + 1 = 14)

NO+ (7 + 8 – 1 = 14); CN+ (6 + 7 – 1 = 12)

We find CN and NO+ both have 14 electrons so they have same bond order. Correct answer is (a).
