Explanation:

Let’s break it down. First, we need to see the logic of the code:

- STROKE ? FLPSUT

Let’s compare each letter in order:

S ? F

T ? L

R ? P

O ? S

K ? U

E ? T

This isn’t a straightforward shift by positions; it looks like the letters have been reordered and replaced.

Now, try to spot a pattern:

- Notice that the letters in "FLPSUT" are not present in "STROKE."

- The replacement seems consistent, so let’s try mapping each letter to its code:

S?F, T?L, R?P, O?S, K?U, E?T

Now, apply this to BRIGHT:

B ? ?

R ? P

I ? ?

G ? ?

H ? ?

T ? L

Look at the options:

1. SGFHQA

2. UIHJSC

3. UJHHCS

4. CSJHIU

Given the replacement mapping above, option 4 (CSJHIU) fits better because the arrangement is somewhat consistent with the logic of “STROKE?FLPSUT.”

So, here’s what’s actually happening:

- Letters are mapped in a particular way that isn't a simple alphabetical shift.

- By analyzing, CSJHIU is the most probable answer.

Correct Answer:

Option 4: CSJHIU

What this really means is you might have gotten tripped up by the swapping and unique code for each letter. Don't sweat it—these types of puzzles can be tricky.
