The first record of patient confidentiality dates to which society?

The choices can be found elsewhere and as follows:

Ancient Greeks
Ancient Egypt
China in the mid-1400s
None of the above

I believe the correct answer is the last option. The first record of patient confidentiality dates to none of the choices. I think the country would be US. The first bill about patient confidentiality was made on the year 1995 in the US. Hope this helps.

That is pretty
