Android intent bring activity to top or create one case necessary

Question

Very simple question I'm starting an Activity and I want to be sure there will be exaclty one of that at the stack...

imagine the stacks:

A B C <- top
C <- top

in Activity C i'm starting A, but if A already exists I want it to be brought to the top instead of create a new one...

Which flags shall i pass to the intent?
