Ahuge, jagged rock sits atop a windy cliffside. over a period of many years, how will the rock most likely change? a) it will become larger and smoother. b) it will become smaller and smoother. c) it will become bigger and less smooth. d) it will become smaller and less smooth.

It will become smaller and less smooth. Only because with the wind blowing sand or other other small items it will cause the rock to be pelted which will chip the surface, breaking and making the rock small and rougher

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.
