In the `alpha`-decay process occuring in different types of nuclei at rest
(i) the `K.E.` of the daughter nucleus is always greater than the `K.E.` of the `alpha`-particle
(ii) the `K.E.` of the daughter nucleus is always less than the `K.E.` of the `alpha`-particle
(iii) the magnitudes of the linear momenta of the `alpha`-particle and the daughter nucleus are always equal
