The common features among CO, CN- and NO are
Bond order three and isoelectronic.
Bond order three and weak field ligands.
Bond order two and -acceptors.
Bond order three and -donors.
A.
Bond order three and isoelectronic.
For the species having same number of electrons, have same bond order.
Number of electrons for CO = 6 + 8 = 14
Number of electrons for CN- = 6 + 7 + 1 = 14
Number of electrons from NO+ = 7 + 8-1= 14
Hence, all the given species are iso-electronic and have same bond-order (three)
Hence, option (a) is the correct answer.
