Well Id say C because I know a lot of people who go and by a at home hiv test and some go to the doctor and check, but once my friend was at the doctors and they asked him if he liked male or females he said both thinking they meant as friends. They checked him for hiv and it was mandatory due to him indirectly saying his was bisexual. If you have government insurance (aka Medicaid) when you go for a check up it is mandated by their insurance policy. Just some extra info (Hope I helped some)
