1.  one smaller nut is tightened over main nut and main nut tightened against smaller one by loosening, creating friction jamming

2.  a slot is cut partly is middle of nut and then slot reduced by tightening a screw

3.  a hard fiber or nylon cotter is recessed in the nut and becomes threaded as the nut is screwed on the bolt causing a tight grip

4.  through slots are made at top and a cotter pin is passed through these and a hole in the bolt, and cotter pin spitted and bent in reverse direction at other end

4
Correct Answer :

through slots are made at top and a cotter pin is passed through these and a hole in the bolt, and cotter pin spitted and bent in reverse direction at other end
