This is the charge-and-parity-conjugate reaction of part (i). There are -channel Z boson and crossed W boson contributions, with all fermion arrows reversed relative to part (i). For matched unpolarized kinematics and negligible CP violation,
(1)
Combining all four results in the regime specified in part (i),
(2)
In particular, conjugating both initial particles restores the part-(i) rate; conjugating the neutrino alone does not. Initial spin polarization and energies near a weak-boson mass require a separate comparison.
