Select the most appropriate Exclamatory form of the sentence given below:

I wish I were an astronaut.

Oh, if I were an astronaut!

The correct answer is Option (3) - Oh, if I were an astronaut!

• Option 1: "I wish that I was an astronaut!"  Not exclamatory — it's just a restatement of the original wish. Also, "was" is less formal than "were" in such hypothetical cases.

• Option 2: "I wish that I could be an astronaut!"  Similar to the original sentence, but still not an exclamatory transformation.

•  Option 3: "Oh, if I were an astronaut!"  Correct exclamatory structure showing desire/regret.

• Option 4: "Alas! I were an astronaut!"  Grammatically incorrect. “Alas” expresses sorrow but must be followed by a complete and correct clause, like “Alas! I am not an astronaut.”
