請問這題如果選項有has been postponed 可選嗎？

5 站洲 扣0說敬光后宮瑟義
ha becen po氏/2nled
The presentation               until the
keynote speaker Wayne Hil arrived.

8   /has postponed

(B) had been postponed
(0)     ostponed
will have been postponed

Answer 1

可能

until ~ arrived
那在他到之後就結束動作了
所以說是過去完成式

現在完成式是過去持續到"現在"
所以應該是不正確的
