how to get instance name on object boolean which value is true

i may have gone further than what i could because i just learned actionscript 3 days ago.

I'm making a simple quiz where I made the answer choices manually, not using the components provided by Adobe Animate. because I can decorate the appearance however I want.

I made movieclip button named answer1 and answer2, then to check if the answer was selected I added a boolean.

e.currentTarget.selected = true;
e.currentTarget.selected = false;

this is my code for the answer button

function clicked(e:MouseEvent): void {
    if (e.currentTarget == answer1) {
        if (e.currentTarget.currentFrame == 1 ) {
        e.currentTarget.nextFrame(); // hover/active button
        e.currentTarget.selected = true;
        } else {
        e.currentTarget.prevFrame(); // hover/active button
        e.currentTarget.selected = false;
        }
        answer2.selected = false;
        answer2.prevFrame();
    } else if (e.currentTarget == answer2) {
        if (e.currentTarget.currentFrame == 1 ) {
        e.currentTarget.nextFrame(); // hover/active button
        e.currentTarget.selected = true;
        } else {
        e.currentTarget.prevFrame(); // hover/active button
        e.currentTarget.selected = false;
        }
        answer1.selected = false;
        answer1.prevFrame();
    }
}

then I made a button to check the answer. but until here I don't know how to check the object that has been selected

function checkAnswer(e: MouseEvent): void {
trace(answer1.selected.name)
}

i want only how can i get the instance name of the boolean object which has the value true.

BTW, if you intend these selectors work as radiogroup (a group of radiobuttons that lets only one of them be selected as the same time), you'd better devise it that way:

function clicked(e:MouseEvent): void
{
    // Define a radiogroup.
    var aGroup:Array = [answer1, answer2];
    
    // Iterate over the group elements and process the click.
    for each (var anAnswer:MovieClip in aGroup)
    {
        if (anAnswer == e.currentTarget)
        {
            anAnswer.selected = !anAnswer.selected;
        }
        else
        {
            anAnswer.selected = false;
        }
        
        // Adjust the current frame according to "selected" value.
        if (anAnswer.selected)
        {
            anAnswer.nextFrame();
        }
        else
        {
            anAnswer.prevFrame();
        }
    }
}

Why? First, it is still shorter than yours even at 2 options. Second, think about adding more than 2 options, like, 10 of them? My code will only need extending the Array of options, yours will get 5 times longer than now.
