Thanks for the question! but the set of possible answers was "too easy": once I saw that B#2 was going to error out while B#3 was not, I didn't look at the subsequent Bs :-).

I concur... but what is easy for one person isn't for another.

That explanation requires expanding slightly, because there is more than one type of temporary table.
Local temporary tables (prefixes with '#') go out of scope when the exec command completes. However, use '##' to create a Global temporary table and the table can be accessed outside of the exec statement that created it.

You are right. But with global temporary table this will be no fun.

I wanted to have it uniform.
