Critical Reasoning (CR) | Re: Mr. Janeck, a permanent resident of a remote island called Hypothetica

Mr. Janeck, a permanent resident of a remote island Hypothetica, owns a luxury sedan. Hence, this sedan must be of the Mersche make.

Which of the following would have to be assumed for the conclusion to hold?

A. None of the luxury sedans owned by any permanent resident of Hypothetica belongs to a non-Mersche brand.[color=#00a651] Good. Mentions all the information.[/color]

B. All luxury sedans in Hypothetica are of Mersche make. Good. If we negate it, conclusion will fold. But does not use all the information in the passage (permanent resident). Too extreme.
