detailed solution

Correct option is D

C2  (8 electrons); KK(σ2s)2(σ2s)2π2px2π2py2 Bond order =(62)/2=2

C2+ (7 electrons);  Bond order =(52)/2=11/2

C2 (9 electrons);  KK(σ2s)2(σ2s)2π2px2π2py2σ2py1 Bond order =(72)/2=212

C22 -(10 electrons);   Bond order =(82)/2=3

Larger the bond order, larger the dissociation energy.
