Adverbs are words that modify verbs, adjectives, or other adverbs, providing more information about an action or description. They typically answer questions like how, when, where, or to what extent.
The correct answer is Adverb of frequency. The word "seldom" in the sentence "Barking dogs seldom bite" indicates how often (or in this case, how infrequently) the action of biting occurs. It directly answers the question "How often?" (rarely, not often), which is the defining characteristic of an adverb of frequency.
Adverb of place is incorrect as it answers "Where?" (e.g., here, there). Interrogative adverb is incorrect as it is used to ask questions (e.g., why, when). Adverb of manner is incorrect as it describes *how* an action is performed (e.g., quickly, slowly), not its frequency.
