The correct answer is (D) has been awarded.
"Our school has been awarded first place" — passive voice, present perfect, correctly describing a recent achievement being shared as news.
The sentence announces a recent event ("exciting news"), so present perfect tense is needed. It must also be passive because the school receives the award, it doesn't give it. Option (D) "has been awarded" satisfies both conditions. Option (A) is active and wrong; (B) is simple past passive; (C) is past perfect active — neither fits the context of a just-announced, current result.
