  • Statement (i) is correct as work done by a force is indeed the product of the force and the displacement in the direction of the force.
  • Statement (ii) is incorrect. Work is a scalar quantity and has only magnitude, not direction.
  • Statement (iii) is correct because an object possessing energy can exert a force on another object, transferring energy and potentially causing displacement.
  • Statement (iv) is correct; the unit of energy is joule (J), the same as the unit of work.
  • Therefore, the correct statements are (iii) and (iv), making Option B the correct answer.
