Please help with a simple Fibonacci question

Hello,

Newbie to forex and I started learning about Fibonacci, because I know so many use them differently I try to read multiple books or watch multi videos to find those using it the same for confirmation that I understand how to use it. I see too many doing the Fibonacci retracement and the expansion differently as in where they start to plot the line.

I'm hoping by the pictures and the notes I left them in can help you to help me understand which is the right way to draw the Fibonacci expansion.

Thank you

C is the way I would have used it, although there are other factors to consider those peaks are suggesting a down trend plus the lower low, a lower high wouldn't put me off but a lower low would.
