Sat question, passive word choice, "shown " grammar [closed]

C is correct. This is the original:

You enter .... You are shown ....

We can combine these two related sentences with a coordinating conjugation:

You enter ..., and you are shown ....

But since the subjects are the same, we can elide the second one and combine the clauses into one compound predicate:

You enter ... and are shown ....

Answer D is not grammatical.
