see..consider 5 readers execute the first statement rc=rc+1 and get pre-empted. So, now value of rc is 5. Now, if any of the readers go to database part, they will not execute down(db) statement because rc is not 1.

Now, one writer can also go in database.

So, option B is true.

But I am not able to find deadlock here.
