Explanation:

The problem practically gives us the answer in its explanation of the various roots, which is nice:

- "a" means "not"

- "morph" means "form"

Essentially, we want to find a word that means "without form", but clearly, because the problem gave us these two roots, it's very likely that the correct answer will have these roots. Looking at the answer choices, only choice A includes both "a" and "morph", and it's correct because "amorphous" literally means "without shape or form".
