there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
