Basic Oracle ?

I am going through some sample test for the DBA exam and I came across the following question:

Which clause would you use to exclude rows from a group calculation?

1. where
2. having
3. order by
4. into

I chose b because it said group calculation. I know that the where condition excludes rows from a select but I assumed that having excludes rows even further after the group by.

Any help would be appreciated.
