DTP is the devil.
I wanted to say B for a second….as vlan1 should never be native for best practice…but DTP IS WAY WAY WAY worse of those two issues.

Why no DTP? You already want trucking on the port so why not leave DTP? Don’t see the downside of having DTP on a port that you want to trunk. So leaning towards B?? Unless is misread the question
