Final answer:
Drivers in the U.S. can typically turn right on a red light after coming to a complete stop and yielding to all traffic, unless a sign or police officer indicates otherwise.
Step-by-step explanation:
In the United States, drivers are generally allowed to turn right on a red light under specific conditions. The correct answer to your question is B) Only after coming to a complete stop and yielding to all traffic. A driver must first come to a full and complete stop, and then only proceed to turn right when it's safe to do so and they have yield to all other traffic and pedestrians. Of course, if there is a "No Turn on Red" sign, or if a police officer signals otherwise, this rule does not apply.
