Solution


The reactivity of aryl halides towards nucleophilic substitution increases if any electron withdrawing group,such as $$NO_2$$ is bonded to the benzene ring at the ortho and para position. 
      
In chlorobenzene, no EWG present. So, it is least reactive. 

In o-nitrochlorbenzene, one EWG is present in the ortho position. 

In o,p-dinitrochlorobenzene, two nitro groups present. So, it is more reactive than o-nitrochlorbenzene. 

In trinitrochlorobenzene, three EWG ($$NO_2$$) present. So, it is most reactive among all the compounds.
