Question

A w= 485
B w=137
C w=97
D w=59

Answer 1

If the motion is in the direction of the force
then 14 * 7 = 98 ft pounds
However you did not specify the direction of the motion.
You imply that the force is in direction 3 i + 4 j but you did not actually say that. You did not even hint at the direction of the motion.
The answer is the distance moved * the component of your 14 lbs in the direction of the motion.
