Explanation:

Let’s break it down:

- We have POK and HLM. The task is to find a pattern.

- POK: P(16), O(15), K(11).

- HLM: H(8), L(12), M(13).

- Now let's check the differences:

- P to H: 16 – 8 = 8 (down by 8)

- O to L: 15 – 12 = 3 (down by 3)

- K to M: 11 – 13 = -2 (up by 2)

What this really means is:

First letter: -8

Second letter: -3

Third letter: +2

Now, apply it to ORT (O, R, T ? 15, 18, 20):

- First letter: O(15) – 8 = 7 ? G

- Second letter: R(18) – 3 = 15 ? O

- Third letter: T(20) + 2 = 22 ? V

So, the answer should be GOV, but GOV is not in your options.

Let’s see what happens with the given options:

- Option 1: QPM (17,16,13)

- Option 2: QOL (17,15,12)

- Option 3: QPL (17,16,12)

- Option 4: QOM (17,15,13)

Comparing the options, none follows the original pattern, but here's a pattern:

- From POK to HLM, if you look for reverse alphabetical order:

- P to H is not reverse. But check the corresponding positions for O/K and L/M? Doesn't fit a mirror pattern.

- It seems the intended answer is pattern-based, possibly on a key, but given the breakdown, none directly work.
