A plot of the number of neutrons $(N)$ against the number of protons ( $P$ )of stable nuclei exhibits upward deviation from linearity for atomic number, $Z>20$. For an unstable nucleus having $N / P$ ratio less than $1$ , the possible mode($s$) of decay is(are)
($A$) $\beta^{-}$-decay ( $\beta$ emission)
($B$) orbital or $K$-electron sasture
($C$) neutron emission
($D$) $\beta^{+}$-decay (positron emission)
