hungary
greece
spain
italy

I don't know of any events in Greece at the time, so I think we can reject this answer.

HUngary is correct, except that it was not independent at the time, but part of the Austrian Empire, so it's already included in the question.

Spain had a little unrest, but not a lot.

The best answer is Italy - it had very important events during this time, for example the revolution in Sicily in 1848.
