The hill is about ________
A 900 metre high B 900-metre high
C 900-metre-high D 900 metres high
请说明理由 谢谢

The hill is about 900-metre-high
C
900-metre-high
900和metre是名词，用“-”号连接后变成形容词词性。

就好像“a nine-year-old boy”,一个道理

i choose D. A similar qusetion:

how old are you?

i am 900 years old

D,名词复数的用法之一，你可以去掉HIGH看看
