答案

dare的用法：dare用作实义动词,此时其后的动词不定式可带to也可不带to,且dare有人称和数以及时态的变化.例如：
I dare to jump down from the top of the wall.我敢从那墙头上跳下来.
She doesn\'t dare (to) meet her teacher\'s eyes.她不敢与老师对视.
2） dare用作情态动词,后跟动词原形,主要用于疑问句、否定句和条件句中.例如：
How dare she do things like that to me?她怎么敢对我做那种事?
-Dare you catch the mouse?你敢去抓那只老鼠吗?
-I daren\'t do that.我不敢抓.
If you dare say that to our teacher,I would vote for you.如果你敢向我们的老师说那件事,我就投你一票.
所以,这里选c,只有c的第二个dare是情态动词.
