In which of the following cases it was held that "there is no distinction between defacto and dejure recognition for the purpose of giving effect to the international acts of the recognised authority"?

Correct option is A

In Luther v. Sagar, it was held that there is no distinction between defacto and dejure recognition when it comes to recognizing and giving effect to international acts of the recognized authority. The judgment clarified that once the authority is recognized, their actions are legally binding regardless of whether the recognition is de facto or de jure.
