A deuteron d captures a charged pion 7 in the / = 1 state, and subsequently decays into a pair of neutrons (n) via strong interaction. Given that the intrinsie parities of r,d and n are -1,+1 and +1 respectively, the spin wavefunction of the final state neutrons is (a) linear combination of a singlet and a triplet (b) singlet (c) triplet (d) doublet
