To see a component's props object, you use the expression...

• A. this.state
• B. this.props
• C. props
• D. component.props

Answer: (B)

Props are the inputs a React component receives from its parent. In a class component, those values live on the component instance as a property called props, so you read them with this.props. That object contains everything the parent passed in, accessible like this.props.title or this.props.onSubmit. The internal state of a component is accessed with this.state, which is separate from props. Using just props would refer to a local variable named props, which isn’t the standard way to access passed-in values inside a class component. In functional components, you’d use the function parameter named props (or destructure it) instead.
