是因为情态动词must选A.还是形容词选B??

B closed
在这里是形容词，并不是动词。close的形容词是要加d的，但是open不用加ed，既可以表示动词，又可以是形容词。
跟情态动词must无关，keep就跟情态动词must有关，用了原形。

短语：【keep sth adj】

要用closed.keep +宾语+adj的意思是“使。。。保持。。。一种状态”。

B closed：关闭的
must后面的动词keep已经用了动词原形了。

keep sth ...让某物处于某种状态
此空中成分为宾语补足语，所以要用形容词，
所以选B.closed

B
和must无关，keep后接形容词表状态
