Explanation:

Alright, let’s break this down step by step:

- Look at the relationship between PRA and SUZ:

- For each letter:

- P (16th letter) goes to S (19th) ? +3

- R (18th) goes to U (21st) ? +3

- A (1st) goes to Z (26th) ? +25 (or, -1)

- So, first two letters increase by 3, but the last jumps sharply back (almost a full circle in the alphabet, A to Z is like -1).

- Now, let’s apply this pattern to “GOS”:

- G ? J (+3)

- O ? R (+3)

- S ? ?

- S is 19th in alphabet. If we apply -1 (like A to Z), S-1 = R.

- So, putting it together: J R R

- But, let’s check the options:

1. JRU

2. JSU

3. JRH

4. JSH

- None of the options are JRR, so let’s check—they may have used +7 for last letter instead of -1, or maybe it’s something tricky. A quick re-check for last letter:

- A (1st) to Z (26th): actually, that's +25, not -1, so maybe it’s +25, so S +25:

- S (19) + 25 = 44 ? go around the English alphabet (26 letters): 44-26=18; 18th letter is R again. So, same as above—J R R.

- Still, that’s not matching. Testing combining the two logics (+3, +3, +7):

- S (19) + 7 = 26 ? 26th letter is Z. But none of the options match that either.

- Checking the third letter in PRA to SUZ: A (1) to Z (26): that's -1.

- So S-1 = 18, which is R. We're circling back to JRR.

- Now, let’s see options for mistakes:

- Only relevant close answer to JRR is JRU (option 1).

- Option 1 fits the +3, +3 pattern, and the last letter remains close in position.

Here’s what this really means: the answer is Option 1: JRU.
