Which statement correctly describes the saturation property of the strong nuclear force?
(a) Each nucleon attracts all other nucleons in the nucleus with equal strength, irrespective of distance.
(b) Each nucleon interacts attractively with only a fixed, small number of nearest neighbours, almost independent of the size of the nucleus.
(c) Because of saturation, the net nuclear force on a nucleon remains the same no matter how many additional nucleons are added to the nucleus.
(d) The strength of the nuclear force keeps increasing without limit as two nucleons approach closer than 1fm.
