As we learnt in 

Bond Order -

Bond order is defined as one half the difference between the number of electrons present in the bonding and the antibonding orbitals.

- wherein

Bond \:Order=\frac{N_{b}-{N_{a}}}{2}

 

Higher the bond order, shorter will be the bond length.Thus NO^{+} is having higher bond order than that of NO\: so\: NO^{+} has shorter bond length


Option 1)

Bond length in NO^{+} is greater than in NO

This option is incorrect. 

Option 2)

Bond length inNO is greater than in NO^{+}

This option is Correct. 

Option 3)

Bond length in NO^{+} is equal to  that in NO

This option is incorrect. 

Option 4)

Bond length is unpredictable.

This option is incorrect.
