I wouldn't say it has no connections, given that it is produced in Germany and was introduced to the German market first in 1967. But yes, it is an italian brand, there is no discussion about that, so Italy should be the right answer.
You should add some more challenging ones: Nidar, Marabou, Fazer and Toms. I really like your quiz idea, I've had the same idea myself, but you certainly beat me to it.
