The correct answer is Garke-garke.
The question is asking which of the options is not a duplicative word. Duplicative words are words that repeat a syllable or a sequence of
syllables, often to emphasize or intensify the meaning. Options are examples of reduplicative words in Hausa, while option "Garke-garke"
is not a valid word in Hausa. Therefore, the correct answer is Garke-garke.
