She speaks very good English. This would be the correct form of B.

A. "She speaks English very well." It's because, based from what I read, adverbs cannot be put between object and verb. The adverb here is, "very well", verb is "speaks" and object is "English".

"She speaks English very well," is the correct sentence. Adjectives usually go in front of the nouns they modify, but adjectives that describe the quality, current state of the noun, as well as an opinion can go after the noun. I hope this helps.
