Answer and Feedback
Answer:C
Feedback:The action in this sentence has been completed recently and we see the result of it in the present. In this case we should use the Present Perfect Tense: has/have + Verb (-ed/Irregular). The adverb 'already' should be placed between the auxiliary verb 'to have' and the verb with -ed or in Past Participle.
