The correct answer is C. gida. The question is asking which of the options is not an adverb (bayanau). Gida is a noun meaning "house" or "home", while the other options - dama (right), gefe (side), gobe (tomorrow), and sama (up/above) - are all adverbs in Hausa. Therefore, the correct answer is C. gida, as it is the only noun among the options.
