Problem in choosing what to play

[sp_mag]

I have an audition in a few days and it requires me to perform there one classical piece I know very well three pieces but I cant decide which one to perform.The pieces are:
1.Mozart sonata in C major k545(whole 3 parts).
2.Hayden sonata in D major Hob:XVI/37(5 and a half pages until the Largo part)
3.Mozart fantasia in D minor k397 (whole)
what should i play?

the one you play best. And oh, you need to learn the op numbers...

I'd recommend doing the D-minor fantasia.  Its transition from minor to major reminds me of the overture to Don Giovanni, and listening to that overture puts me in a good mood to do the piece.  The cadenzas can be done very fast with the right fingering.  It's fun.
