D
Correct answer
Explanation
The Fidelius Charm is a powerful protective spell that conceals a secret within a living soul, making the location invisible to anyone who hasn't been told the secret by the Secret Keeper. This charm protected the Order of the Phoenix headquarters at Grimmauld Place. The Disillusionment Charm only makes objects blend into surroundings, Shield Charms block specific spells, and an Invisibility Charm isn't an established canonical spell in the same way.
