The answer would the A.
It is best to go with traffic and not tail-gate someone, but not be too under the limit so that other vehicles would not be attempting to get ahead of you, for it can be dangerous.
- Speeding tickets are, for the most part, not handed out when yo hate going with the rest of traffic, so long you are not speeding past other vehicles, weaving, etc. To make this simpler: Speed limit - 5 above.
Going UNDER the speed limit does nothing for you except ensure people in vehicles to be angry at you.
