Which of the following statements correctly defines balanced forces acting on a body?
(a) Their vector sum is non-zero but constant, so the body moves with constant velocity.
(b) They are equal and opposite action–reaction forces acting on two different bodies, hence neither body accelerates.
(c) Their vector sum is zero, so the body’s state of motion does not change.
(d) Their algebraic sum is zero only when the body is at rest; if the body is moving, they become unbalanced.
