C because it sounds more formal and like you know what you are talking about !
B. moderate is the answer
Your rights are to remain silent if anything they find rises question to them and they do question you , and you can also not comply to a search but that would make you look suspicious so if you don't have anything to hide don't be making it hard on everyone for no reason but if you do you reserve the right to say no. The only time you don't have a say in it is like if there was a crime and it happened in the work place since it is not owned by you you just work there if whomever owns it says they can search anything thing then you have no say because it is not your property i hoped this helped :)
