Solution

The functional component is incorrect due to several reasons:

  1. The import statements should be at the top of the file, not inside the function.
  2. The function should return the JSX directly, not inside another return statement.
  3. The class attribute should be replaced with className because class is a reserved word in JavaScript.
  4. The function should be declared before it is exported.

Here is the corrected version:

import React from 'react';
import './master.css';

function Headline() {
    return (
        <h1 className="headline">Hello World!</h1>
    );
}

export default Headline;
