This example demonstrates a simple React dropdown menu for selecting a pet, with a large, readable interface optimized for demonstration purposes. The code uses React 16.9.0 and ReactDOM to render a single `<select>` element containing seven options, including a placeholder prompt. Styling is applied via inline CSS in the HTML file, adjusting font sizes for the label and select controls. The application mounts to a root `<div>` element, and the implementation is minimal, showing basic form control composition without any external data sources or event handling logic.
