How can i use QnAMaker to provide random answers to same query

To achieve this requirement, you can try this approach:

1) Add a QnA pair and use a special character (such as |) to split answers for question how are you?

2) Override the RespondFromQnAMakerResultAsync method, and split response and retrieve answer randomly in this method

protected override async Task RespondFromQnAMakerResultAsync(IDialogContext context, IMessageActivity message, QnAMakerResults result)
{
    // This will only be called if Answers isn't empty

    var response = result.Answers.First().Answer;
    var answersforhowareyou = response.Split('|');

    if (answersforhowareyou.Count() > 1)
    {
        Random rnd = new Random();
        int index = rnd.Next(answersforhowareyou.Count());

        response = answersforhowareyou[index];
    }

    await context.PostAsync(response);
}

Test result:
