Which sentence correctly treats an additive phrase as separate from the grammatical head subject?

The manager, together with assistants, prepare the room each morning.
The assistants, accompanied by the manager, is preparing the display today.
The assistants, accompanied by the manager, prepare the room quietly each morning.✓Richtige Antwort
Erklärung
The assistants, accompanied by the manager, prepare the room uses plural agreement with assistants. The additive expressions do not create or replace the head subject, so prepares after assistants and prepare after manager reverse the required agreement; is preparing also mismatches its plural head.
