The correct option is J “proven is that” since no comma is needed after the word “proven”. Grammatically speaking, commas are used to help in the meaning of a sentence by grouping and separating words or clauses. By using commas, a sentence can avoid misunderstanding, but in this case the comma is not necessary to have a clear meaning on its own.
