All of them are wrong.1. BN(O) is a nationality. The key is this is the only nationality you have.2. Not having a HKSAR Passport does not mean you are not a Chinese citizen. (Home Office will ask for proof from the Immigration Department that you are denied for a HKSAR Passport).So in a simple way to say, if you can't get a HKSAR Passport at all and you don't hold any nationalities beside BN(O), then you will be eligible to become a British Citizen.
