A homeowner wants to reduce the environmental damage of the energy source used to heat her home. (D.  Wind) I took the test

i believe the answer is c and this is only worth 10 points you might wanna change it

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

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

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.
