(b) English is spoken very well by her.

I guess you can, but the sentences look awkward to me... Why not simply say "she speaks English very well"?
I want the sentence in passive voice. Which one is better?

What do you think?
I think it's not a sentence that lends itself to the passive.
Why?

I agree with GG.
I think we mostly use the passive when the subject is unknown or unimportant in the context, which is not the case here.
Exactly.

There are some instances when it would work, like English is spoken well by Susan, but poorly by James. Even so, it's rather stilted.
