Which of the following correctly describes how the sign of linear momentum of a particle moving in one dimension is decided once a coordinate axis is chosen?
(a) The sign is always positive because mass is positive.
(b) The sign depends on acceleration, not velocity.
(c) The sign is the same as the chosen sign of velocity.
(d) The sign is always negative if the particle moves left.
