Question

aud = \hear\ auto = \self\ mob = \move\ based on the list of word roots, what is the correct spelling of a word that means \a vehicle that moves by itself\? automobile audimobile automobile

Explanation:

The word - root "auto" means "self" and "mob" means "move". A vehicle that moves by itself combines these two roots. "Automobile" is the correct term formed from these roots as "aud" means "hear" and has no relation to the meaning of a self - moving vehicle.

Answer:

automobile
