This quiz has been redone to include only the basic instruments. The number of possible other instruments, including percussion, is almost too numerous to mention, and there is no "official" instrumentation.
Yes, I just saw that! This quiz is simultaneously very easy (and given it took me 21 seconds, I think the time limit could probably be reduced a bit from 5 minutes...) and at the same time, the hardest quiz on the site right now, given that you need to score 20 out of 12 on it for the music badge.
[Spoiler Alert] There's a particular order in which these should be listed in: Flute, Oboe, Clarinet, Bassoon, Horn, Trumpet, Trombone, Tuba, [Add timpani, it's the one percussion standard in the orchestra most of the time], Violin, Viola, Bass
Sax usually isn't in full symphony orchestra pieces, since it wasn't invented until long after most were written. Modern concert band pieces do feature it though.
if it were to be, a lot of things would likely be added
