Pump impeller

My Sister has a pool pump (Jandy) And I think it’s a one H.P. motor… but not sure about whether it’s a 3/4 H.P. uprated or what.
So the label on the side of the motor says: “1.0 HP UPRATE” and she says they installed it in 2005.
So my question is: Which impeller and seal kit do I need to order?

4590-42635005 IMPELLER 3/4 HP, 1 HP UPRATE$88.99

-OR-

24590-43635006 IMPELLER 1 HP FULL, 1 1/2 HP UPRATE$72.99
