Explanation:

- To solve the analogy, let's understand the transformation from JKLM to HLKO.

- Each letter is shifted:

- J (10) becomes H (8): a backward shift of 2.

- K (11) becomes L (12): a forward shift of 1.

- L (12) becomes K (11): a backward shift of 1.

- M (13) becomes O (15): a forward shift of 2.

- Now, apply the same pattern to PQRS:

- P (16) becomes N (14): shift backward by 2.

- Q (17) becomes R (18): shift forward by 1.

- R (18) becomes Q (17): shift backward by 1.

- S (19) becomes U (21): shift forward by 2.

- This transformation results in NRQU.

- Therefore, the correct answer is:

Option 1: NRQU
