Step 4: Display Questions and Options
function loadQuestion() {
const q = quizData[currentQuestion];
questionEl.innerText = q.question;

const selected = document.querySelector('input[name="answer"]:checked');
if(selected && selected.value === quizData[currentQuestion].correct){
score++;
}
currentQuestion++;
if(currentQuestion < quizData.length){
loadQuestion();
