Correct option is A
In part A, “has” must be replaced with “has been” as the sentence requires a present perfect tense.
Note: The Present Perfect is connected to the present and may refer to a completed action. However, we are not interested in the time of the action, rather in the results of that action as they affect us now. That is why the tense is called the
Present Perfect. Ex-As I
have broken my leg, I can't go dancing.
