I had to read this paragraph several times before I understood what you are saying
here. Could you please refrain from using abbreviations such as "abt" and "u", it
only makes people want to delete your message and go to the next one.
As for the original question:

Scenario a) will happen if optimistic locking is being used, and b) if
pessimistic. Note that on a clustered server, it will probably always be
optimistic.

Then again, it depends on the kind of locking. Optimistic will defer this
decision to the database, pessimistic will prevent more than one client to lock a
PK at a time.
