"Fault Q occurred before layer K was deposited." is correct.
Explanation: Fault Q cuts and offsets the lower layers (B and W), so it formed after B and W were deposited. The upper layers (E and K) are not cut or displaced by the fault, so they were deposited after the fault—therefore the fault happened before K (and E) was deposited.
