The correct option is A Adverb of Time
The adverb 'already' modifies the verb 'spoken'. It hints at the hour of speaking giving us a sense of time. Hence, Option A - Adverb of Time is correct.
Option B is incorrect because the adverb 'already' doesn't answer the question 'how' or 'in what manner' the speaking was done.
Option C is incorrect because the adverb doesn't indicate any place of reference.
Option D is incorrect because it doesn't speak anything about the frequency of the action.
