Poll is now closed.
Answer is: A is lossless
6 people voted for A, and 6 people voted for B. So basically people are just blindly guessing...
Conclusion is that we generally cannot tell the difference between AAC 256kbps and Lossless.
The pursue of 24bit+ audio and higher bitrate than 48khz is probably not worth it as well.
If you voted for A, you likely only guessed it right
If you voted for B, don't feel bad, I might just saved you from buying that $1000 DAC.
On a side note, This experiment has a sample of 16 and a track downloaded from internet archive. Any "truth" drawn from this experiment is only as real as the invisible pink unicorn.

Here is an interesting experiment I always wanted to do
I have an uncompressed wav file, then I compressed it to AAC 256kbps and then decoded it back to wav. I was careful during the conversions so both file is the same size

B: https://drive.google.com/file/d/1-oJLTa5YOcB839fANwgIUcL0N_LQGAY9/view?usp=sharing
Please pick which one do you think sounded better in the poll
Please ask your friend to cast a vote so we get more data.
Poll will be closed in 7 days and I will post result to see if people can actually hear the difference.
Please do not use any software out there to "see" which file is compressed before casting a vote.
Please do not discuss what you have voted for or what the status of the poll is
To prove that one of these is compressed significantly, I attached a spectrum view where top 2 channels is the uncompressed file and the bottom two is the compressed one.
I got the music from Internet Archive https://archive.org/details/EFJAI1003/06-IfRightIsWrongLeftMustBeRight-Edit.flac
