During $\left({\mathrm{\beta }}^{-}\right)$ decay (beta minus), the emission of antinenutrino particle is supported by which of the following statement(S)
A) Angular momentum conservation holds good in any nuclear reaction
B) Linear momentum conservation holds good in any nuclear reaction
C) The KE of emitted $\mathrm{\beta }$-particle varies in any nuclear reaction

If a beta decay is associated with the relation${}_0{}^{1}n\to {}_1{}^{1}p+{}_{-1}{}^{0}e$

to balance the spin quantum no  or angular momentum another particle need to be there as proton, neutron and electron all have spin quantum number 1/2

many experimental results shows until and unless another particle is considered linear momentum and energy conservation can not be justified.
