I circled this question AND went back to it--I wavered between C and D for so long. The key here is to realize that we are comparing:

-emissions of COAL PLANTS

-speed (NOT. EMISSIONS. I repeat, NOT [presumably, gas] emissions) of CARS

I somehow had in my head the notion that the car is still "running" (gas, emitting) at stoplights but if it is properly at a STOPlight the speed is 0mph, unless you're violating the law or something.
