Just wanna say, I got this question correct both times, and actually understood how I got it correct but doing the diagram. YAY ME !!!

I'm sorry but I am just not understanding the diagramming, and it's so frustrating.

Went with C the first time around and for the Blind Review answer correct. I am not a diagram person, all of that just confuses me a little. Like sometime I get it and other times I be completely lost.
