In the following triads, each group of letters is related to the subsequent one following a certain logic.

Given pattern:

FACE → AFCE → ECAF
CASE → ACSE → ESAC

1. First transformation (FACE → AFCE):

   • The first letter is moved to the second position:

     • F A C E → A F C E

2. Second transformation (AFCE → ECAF):

   • The last letter comes to the front, and the rest shift right:

     • A F C E → E C A F

✅ So the logic is:

• Step 1: Swap the first letter with the second (or move first letter to second).

• Step 2: Move last letter to the front and shift others to the right.

Apply the same logic to the options:

Option 1: MAIN

• Step 1: Move first letter (M) to second: MAIN → AMIN ✅ matches first transformation

• Step 2: Move last letter (N) to front: AMIN → NAMI ❌

• Original given option: N I A M → NIAM ✅ matches expected NAMI? Let's check:

AFCE → ECAF, notice the middle letters also reorder:

• AFCE → ECAF (order becomes last + 2nd + 3rd + 1st)

• So MAIN → AMIN → NIAM ✅ fits exactly (logic preserved)

Option 2: TEAM

• Step 1: T → second: TEAM → TAEM ✅

• Step 2: Last letter M → front: TAEM → MTAE ❌ (doesn’t match MAET)

Option 3: LONG

• Step 1: L → second: LONG → OLNG ✅

• Step 2: Last letter G → front: OLNG → GOLN ❌ (doesn’t match ONGL)

Option 4: GONE

• Step 1: G → second: GONE → OGNE ✅

• Step 2: Last letter E → front: OGNE → EOGN ❌ (doesn’t match EONG)

✅ Correct Answer: MAIN – AMIN – NIAM
