The phrase is incorrect and does not make much sense.
Following the options we can understand that the correct word here would be the adverb 'conclusively' followed with the verb 'proves.' The word 'that' is mandatory after it to state what was proved.
Thus only option B fulfills the condition here.
Option A is incorrect as the adverb is missing.
Option C is incorrectly structured.
