'Hallo' is indeed the standard greeting in German, Dutch (official spelling in Netherlands), and Norwegian. In German, 'Hallo' is a common informal greeting. In Dutch, both 'Hallo' and 'Hoi' are used. In Norwegian, 'Hallo' is used alongside 'Hei'. Finnish uses 'Hei' not 'Hallo' for greetings, so option B is correctly excluded. This is a good multilingual greeting word recognition question testing basic vocabulary across related Germanic and Northern European languages.
