Which of the following statements correctly defines balanced forces acting on an object?
(a) Equal forces acting at right angles to each other are balanced and keep the object at rest.
(b) Two forces of equal magnitude acting in the same direction are balanced because their magnitudes are equal.
(c) The forces act from opposite directions, are equal in magnitude, and do not change the object’s state of motion.
(d) Unequal forces acting in opposite directions keep the object moving at a constant speed, so they are balanced.
