In a React class component, a render method is defined as which of the following?

• A. A static method
• B. A property named render whose value is a function
• C. A nested object
• D. A lifecycle method

Answer: (B)

Render in a React class component is the function that determines what the UI should look like. In the class syntax, you provide a render function that belongs to the component instance; it’s a property named render whose value is a function. React calls this function on the component instance to obtain the JSX it should render, which is why the render method has access to instance data like this.props and this.state. This isn’t a static method, because React uses the instance to read props and state during rendering. It’s not a nested object, and while it’s central to the rendering process, it isn’t one of the explicit lifecycle methods like componentDidMount. So describing render as a property named render whose value is a function aligns with how class components expose the rendering logic.
