Help me a question!

題目：

Help me a question!
_____ from the hill,the little village looks all the more beautiful.
A.To see B.Being seen C.Seeing D.Seen
Key:D
Why?

解答：

to see和seeing是主動形式,表示主語要發出這個動作,然而,the village發不出這個動作.
being seen表示正在被看,意思不合適
seen是過去分詞短語作條件狀語,表示主語被看
等於：If it is seen from the hill,the little village looks all the more beautiful.
