Explanation:

Let’s break down each option:

- Option 1: Right of Passage case

The International Court of Justice (ICJ) gave a final judgment in this case (Portugal v. India, 1960).

- Option 2: Nuclear Test case

In this case (Australia/New Zealand v. France, 1974), the ICJ refrained from giving a final judgment as France made undertakings making the case moot; the Court recognized these and declined to decide on the merits.

- Option 3: Corfu Channel case

A final judgment was delivered by the ICJ (United Kingdom v. Albania, 1949).

- Option 4: None of the above

Not applicable because option 2 is correct.

So, the correct answer is Option 2: Nuclear Test case
