Analyzing Letter Group Transformations

The question asks to identify the logic connecting letter groups in triads and find the option that follows the same pattern. We analyze the transformations in the correct option, FIRM - RFIM - MRIF.

Step 1: FIRM to RFIM Transformation

The transformation from FIRM to RFIM involves rearranging the letters based on their positions:

• The 3rd letter ('R') moves to the 1st position.
• The 1st letter ('F') moves to the 2nd position.
• The 2nd letter ('I') moves to the 3rd position.
• The 4th letter ('M') remains in the 4th position.

This corresponds to the positional permutation (3 1 2 4).

Step 2: RFIM to MRIF Transformation

The transformation from RFIM to MRIF follows a different positional rearrangement:

• The 4th letter ('M') moves to the 1st position.
• The 1st letter ('R') moves to the 2nd position.
• The 3rd letter ('I') remains in the 3rd position.
• The 2nd letter ('F') moves to the 4th position.

This corresponds to the positional permutation (4 1 3 2).

Conclusion: Pattern Verification

Option 4, FIRM - RFIM - MRIF, exhibits a two-step transformation process:

1. Apply permutation (3 1 2 4).
2. Apply permutation (4 1 3 2).

This specific sequence of transformations defines the logic that needs to be matched. Option 4 correctly follows this established pattern.
