Doubts about the use of StopWords

I would like to ask a question about what is the best use of stop words. I have a filter (option A) with passing all stopwords and the other option is to create a filter for each language (option B). In any case would I reduce the size of the index?

Option A

      "stop_words_filter": {
          "type": "stop",
          "stopwords": [

Option B

        "brazilian_stop_filter": {
          "type": "stop",
          "stopwords": "_brazilian_"
