You can pass json object / json array using @Body by converting the json model to POJO ( using GSON) .

Try the following way.

Your API endpoint

@POST("url")
Call<ResponseBody> yourAPi(@Body JSONArray jsonArray);

And API call using param data

String[] answer = {"aaa","bbb","ccc"}
JSONArray jsArray= new JSONArray();
try {
    for(int i = 0; i < answer.length; i++) {
        JSONObject object = new JSONObject();
        object.put("question_id",i+1);
        object.put("answer",answer[i]);
        jsArray.put(object);
    }

} catch (JSONException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}   
// here you can call your api 
Call<ResponseBody> call =  yourApiService.yourAPi(jsArray);
// ........
