Mounting lifecycle events only execute ...

• A. The First Time That A Component Renders
• B. During Every Render
• C. Just Before Unmount
• D. After Updates

Answer: (A)

Mounting lifecycle events happen only when a component is added to the DOM for the first time. This occurs after the component is created and renders for the first time, marking the initial mount (for class components, methods like componentDidMount run after that first render). They don’t run on subsequent renders, which are handled by the updating phase (componentDidUpdate) or by unmounting (componentWillUnmount) when the component is removed. So the best description is that these events occur during the initial render.
