I'm rushing out now so I'll post my reasons later but after a qui
ck look I'd say A and C are close for the best with A just taking it for me, so....
1st.....A
2nd.....C
3rd.....B
Editted later: Its dificult without knowing the size and age of the koi, for me anyway, but my opinion from those photo's for what its worth. A has the better body shape and it even looks male from the pecs but again could just be the photo? B body shape doesnt look hot and C looks as though it could be younger than the others? Always hard from pictures though as it could simply be a 'bad' angle/moment/position etc. All three have dark looking heads but C looks about the best. In terms of pattern, A has by far the most interesting Inazuma style pattern, C is ok and B pattern does nothing at all for me, too little Hi and not particularly well balanced. As I said, A gets my vote as it looks more finished but B runs it close as it looks to be more about potential.
Obviously only my opinion and I'm usually way off
