A is the final answer! :)
When green, the signal means D. all of the above.
A green traffic signal means that you have the right-of-way, but you must yield to pedestrians and vehicles already in the intersection. If you hesitate or slow down, you may cause an accident or hold up traffic behind you, so it is important that you move swiftly and carefully to avoid causing any problems.
I believe the answer is UDP (User Datagram Protocol) because it creates the packets that are sent are unacknowledged so latency is decreased.
9 is B, and 10 is D I think ... brainliest pls
