Lets take a look at each of the graphs to identify the correlation.
Graph A shows a decrease in speed per time, this could be our answer.
Graph B shows an increase in speed per time, this is not our answer.
Graph C shows a constant in speed per time, this is not our answer.
Graph D is the same as Graph B but with a different starting point, this is also not our answer.
When we are approaching a stop light, we need to slow down.
This means that the only option is Graph A.
I hope this helps! :)
