Which prefix means 'away from'

Explanation:
The concept being tested is how prefixes convey direction or action. The prefix that means away from is de-. It signals removal, separation, or reversal—moving away from the original state or object. You can see this in words like detach (to pull away), dehydrate (to remove water), or devalue (to reduce value). The other prefixes don’t carry that exact sense: a- often means not or without, deca- means ten, and circum- means around. So de- is the best fit for the idea of moving away from.
