Do I buy an outer or inner wheel bearing?

I'm replacing my front wheel bearings on an AWD car. Do I buy the Inner or Outer wheel bearing? It gives both options and I don't know which one to buy. Do I buy both?

Thanks.

Edit: Wheres the delete button?

I take it you saw the difference. In case the parts guy doesn't tell you, make sure you pick up the inner and outer seals. There isn't any way to reuse the old ones.

When I ordered my front wheel bearing kit from Erik at JNZ it only came with one bearing per-side for the front end and a few seals / dust shields
