Answer:
A. Ben and Akello's Car
Explanation:
If two people own one thing and share ownership of an object or objects, the possessive adjective is always connected to the second name or the last name in a group of names, which mark one group or a couple.
When it said Ben and Akello's car that means it is their car and they both are owners.
If two people own duplicate objects but everyone has its own, the possessive adjectives are given to the two persons to emphasize their ownership.
