What happens when the following render() method executes?
render() {
return (
<div>
<h1>Hello, World!</h1>
</div>
);
}
It creates a new component called <h1> inside a <div> element.
It returns the HTML markup <div><h1>Hello, World!</h1></div>.
It updates the content of an existing <h1> element with the text "Hello, World!".
It updates the state of the parent component.
Correct: B
The render() method in React is responsible for generating the HTML markup that represents the component's UI. In this case, when the render() method executes, it returns the HTML markup <div><h1>Hello, World!</h1></div>. This markup will be rendered by React and displayed on the web page.
