What is the magnitude of the resultant of parallel force system as shown in the figure ?-A-70 kNmB-zeroC-70 KNm couple anti clock wiseD-90 KN veritical force and a moment of 70 kNm clock wise.-C-70 KNm couple anti clock wise

C 70 KNm couple anti clock wise Answer C is correct. It Considering all the forces take moment 1st left to end it will 70 kNm, 2nd from right it will be 70 kNm so the total system will rotate at a couple 70 kNm.
