Suppose that a constant force (F) acts on an object and object is moved through a distance (s) along the direction of the force (F) work done is equal to

both B and C

the product of the force (F) and the distance (s) moved

$\mathrm{W}=\mathrm{F}\times \mathrm{S}$ when force and distance must be in same direction

when force is not along the direction of motion then w = component of force in that direction of motion × distance moved
