Not quite. The correct answer is highlighted.
Correct answer to question 1 (General Knowledge): Take the vehicle out of service until the tire is replaced
Why
A bulge means the tire's internal structure is damaged and it can fail without warning, including a blowout at speed. It must be replaced before the vehicle goes back into service, not just monitored or reinflated.
