A pet-selection menu demonstrates stateful user input in a React component. The app shows a static list of six animal options in a native HTML `<select>` element, initially set to "hamster" via `useState`. Built with React and rendered through `ReactDOM.render`, the `Dropdown` component receives the options and selected value, then invokes `onSelectedValueChange` to update the displayed choice in response to user interaction. The interface is styled with large fonts for labels and the dropdown.
