• Option B: Oral fluid tests detect HIV antibodies (the antibodies in oral fluid are from blood, so it's related to detecting HIV antibodies in the body's system, though sample is oral fluid).
• Option C: Oral fluid tests require a small sample of oral fluid (some related tests may also use blood, and oral fluid test itself needs oral fluid sample, and the option includes blood or oral fluid which is consistent with related testing methods).
