I need help with this error, I don't know how to correct or fix it

Not all paths are returning a string. Or you need to declare the type of your function as string | void or you need to add return ''; at the end of your function. Should do the trick!

You got this error because you miss the else condition.

if(respuesta === this.opcionSeleccionada){
    return 'active text-light';
}else{
    //Here you need to return something.
}
