Why is this answer correct?

Anyone who moves must register within two weeks with the registration authority, the residents' registration office (§ 17 Federal Registration Act). Answer a is therefore correct. The registry office (b) is responsible for births, marriages and deaths, while the public order office (c) and the trade office (d) deal with other matters.

Moving? Register at the residents' registration office within two weeks.
