In English expression:
It is very common to use the present tense to indicate the action to be taken

Cindy, () to be here at 8 o'clock A.is sureB.is Sure that C.will be sured.be sure!

First of all, B: because it is used to connect the following sentence, so it must be followed by a complete sentence. This is a simple object clause (this is a kind of conjunction with that, and another type is connected with if / whether). You can see that the space in the title is followed by to be... This is the infinitive of the verb, which is not considered to be a complete sentence
C: if you choose C, the comma after Cindy should be removed, and the subject must be followed before will. It is not possible to put will at the beginning of the second sentence alone
Finally, D: we can't use the original form of be verb here, because Cindy is the third person singular, so the verb be can be used only when it is changed into is
If you understand, you should adopt it. If you don't understand, ask again

She is to be here by ten o'clock?

Be to do means to
Is to be here is the usage of be to do

B.A. sure, here is it
B. Sure, here you are
