Although, I don't think that "B" should even be an option as the answer is clear. No a/c means less drag on the engine, and all windows closed means less air drag which in turn means less drag on the engine.
However, running with the a/c off and the windows up in the summer time in the more tropic areas of the world when you have a car with a perfectly functioning a/c system, I'm willing to sacrifice a couple MPG to be comfortable. The a/c in my first vehicle died six months after I bought it and I couldn't afford to get it fixed. I never want to repeat that ever again.

I could believe the text in bold easily. I have learned alot welding an older unibody.
it is even tougher than todays SECC computer case metal squishing like playdoh...(23 year old car)
+1 for A/C reducing resonance..it cools more than people, and keeping air clean, and electricl... even the engine gains more power. Most need to be into heavy welding of cars to know the resonance I refer to. It is not even detectable by people. A/C always helps it.
I also learned, if volume permitting, you can turn the car into a compressor, it is an upside down geo thermal trick....use the compression, and not the air down low. I would not even know how to expain myself.
This subject has bothered me since sitting nice and cool all year round in a big four door sedan...the little cars are roasters. Finding a way to keep cool (ambiguous) with smaller stuff is a tough thing to do.
