The correct pairs are the 1st, 2nd, and 4th choices.

- Unconfined (X): contains the water table; its upper surface is at atmospheric pressure.
- Confined (Y): found between (or beneath) impermeable layers and the water is under pressure.

The 3rd choice is wrong because it swaps the two aquifer types.
