Cryolite consists of:

Explanation:
Cryolite is a compound with the formula Na3AlF6, so it contains sodium (Na), aluminum (Al), and fluoride (F). That composition directly matches the listing for Na, Al, and F, making it the correct match. The other options bring in elements not part of cryolite—such as nitrogen and chlorine, or iron and potassium—so they don’t describe this compound. In addition, cryolite’s fluoride component is what gives it its distinctive role in industry, helping to lower the melting point of alumina during aluminum production.
