By far the best option is missing from your poll, keep people home until testing and protective supplies are greatly ramped up, 4 to 6 weeks, then test, test, and test some more. Especially, the asymptomatic need to be tested -- the exact opposite of what we are doing! If someone tests positive for the virus but no symptoms, they need to be quarantined through the incubation period then tested again for anti-bodies, if still asymptomatic.
Testing 265Mil people every day or 2 at the most is kinda tricky and expensive and any less than that, just isn't worth doing, it's worth it for compiling stat's but that's about it.
Anti Bodies test, then saying you've had it, here is a ID Badge, you can go back to work, walk around, go to the pub, avoid the cues to get into tesco's on the other hand, very useful.
