Problem

Which of the following nuclear equations most correctly represents the decay of carbon-14 to nitrogen-14 while satisfying all conservation laws? a)

_{6}^{14}\text{C}\;\rightarrow\;_{7}^{14}\text{N}+\beta^{-}

_{6}^{14}\text{C}\;\rightarrow\;_{5}^{14}\text{B}+\beta^{-}+\bar{\nu}_e

_{6}^{14}\text{C}\;\rightarrow\;_{7}^{14}\text{N}+\beta^{-}+\bar{\nu}_e

_{6}^{14}\text{C}\;\rightarrow\;_{7}^{14}\text{N}+\beta^{+}+\nu_{e}
