(If I hadn't shared them) which would be the best password and why?

A) WinterMoon38
B) Flame!Rider204
C) J7$kP2!mQx9#L
D) Echo-Bicycle-Violet-77&

@protonprivacy C, the rest include dictionary words? (Assuming best means strongest)

@eibhinn

Dictionary words aren't a problem unless you only have one.

Crunching a random string of characters is only as strong as the string is long, so 13 characters like in C is not great.
