How can I change radiobutton content?

RadioButton

I have a question for you. I would like to set my WPF application to change my RadioButton only to their own content.I'm trying to create a math quiz where the user could choose one of three options.

I tried the code below.

I prefer to send the whole code here so as not to miss anything (yes, it is badly written but perhaps functional). My problem is that I would like to Radiobutton(firstOption, secondOption, thirdOption)assign values ​​to their content so that one was correct. I would assign values ​​according to what the mark is as in the individual examples( for example the user selects a plus, which is calculated as follows

if (mark.Text == "+")
                    {
                        int total = (firstN + secondN);
                        firstT.Text = firstN.ToString();
                        secondT.Text = secondN.ToString();
                        result.Text = total.ToString();

                    }

and one of the options would work out accordingly, with different results being palpable.

But I have no idea how to assign it there.

If anyone has any questions, write me in the comments, I apologize for the combination of languages. I hope it's at least a little obvious what I mean.

Thank you all for any advice.

What I have tried:

List<string> list = new List<string> { "1", "2", "3" };//is there any way to add those options here?
        public void ShuffleText()
        {
            var rand = new Random();
            var shuffledText = list.OrderBy(x => rand.Next(list.Count)).ToList();
            var radioButtons = new[] { firstOption, secondOption, thirdOption };

            for (int i = 0; i < radioButtons.Length; i++)
            {
                radioButtons[i].Content = shuffledText[i];
            }
        }

        private void control_Click(object sender, RoutedEventArgs e)
        {

            timer.Value += 1;
            shiftTimer.Start();
            if (vybOp == 0 || vybOp == 2 || vybOp == 4 || vybOp == 6)//this is enumeration selected operations
            {
                var answerRadioButtons = new RadioButton[] { firstOption, secondOption, thirdOption };
                var correctAnswerButtonFound = false;
                foreach (var answerButton in answerRadioButtons)
                {
                    if (answerButton.IsChecked==true)
                    {

                        if (answerButton.Content == result.Text)
                        {

                            correctAnswerButtonFound = true;
                        }
