Explanation:

Here’s the thing about the origin of Droit Administratif:

- Option 1: USA — The United States doesn’t have a formal system like Droit Administratif. They use general courts for administrative law, not a separate system.

- Option 2: U.K — The British system relies heavily on common law and doesn’t separate administrative courts from ordinary courts. So, not here either.

- Option 3: Germany — Germany’s administrative law grew later and was influenced by ideas elsewhere, but it didn’t originate Droit Administratif.

- Option 4: FRANCE — This is the birthplace. The French came up with Droit Administratif, especially after the French Revolution. It’s a whole separate legal system for state and administrative matters, handled by special administrative courts.
