Cycle c would be your best choice bro. I would provably lower the doses a bit and drop the var. even at your goal of 13% you wont notice much. You are on your fourth cycle and tren should be saved until you have more experience. 450mg is also way to much to be running for your first time. If you want cycle a, drop the tren. Cycle b isn't a good one either. When you are ready to run tren, try it with test alone. That way you can see what it really does.

First, getting gains and dropping fat at the same time is extremely hard to do and is only accomplished in the kitchen and the gym. No compound will magically do that for you. So get the whole idea out of your mind.
I honestly would wait on using the Tren for a few more cycles. You still are very young in age and cycle experience. I like the Prop/NPP/Var cycle the best for your goals.
Back to the Tren:-) it really isn't a compound to be taken lightly or taken too soon in ur AAS development. It really is meant for the hardcore BB'ers and powerlifters. It has been sensationalized to a degree that everybody thinks it is the only compound that will give you crazy strength gains and melt the fat away. That IMO is not the case there are other compounds such as EQ that give me clean waterless gains. Consider the sides that come with it also. It has great benefits but can lead to serious emotional instability/depression. I have experienced both from it.
Wait a few more cycles and try some other compounds.
