A forced stop is stopping not only because of a malfunction or danger, but also because of an obstacle that has appeared on the road or a prohibiting traffic light signal, so all the listed cases are correct.
A forced stop is deliberately stopping a vehicle because of a malfunction, danger from the load, the condition of the driver or passenger, or an obstacle that has appeared on the road, and also in order to obey a prohibiting signal of a traffic light or traffic controller, to give way, or to avoid hitting something (article 2). The listed cases fit this definition, so “in all the cases above” is correct.
Option 1. Obeying a prohibiting traffic light signal is named directly in the definition, but choosing only this case is incomplete.
Option 2. A traffic jam is an obstacle that has appeared on the road, but choosing only this case is incomplete.
Option 3. This is a correct case, but choosing only it is incomplete: the others count too.
