Logic Identification: Letter Permutation

The problem requires identifying a pattern of letter rearrangement from the first pair ($INTERFERENCE$ : $TNIFEREERECN$) and applying it to the second pair ($OSCILLATIONS$ : ?).

Analyzing $INTERFERENCE$ (12 letters) transforming into $TNIFEREERECN$ (12 letters), we observe it's a permutation of letters. We determine the specific permutation rule by mapping each letter in the transformed word back to its original position in $INTERFERENCE$.

Original word: $INTERFERENCE$

Positions: 1 2 3 4 5 6 7 8 9 10 11 12

Letters: $I N T E R F E R E N C E$

Transformed: $T N I F E R E E R E C N$

By comparing the positions, we find the sequence of original positions that form the transformed word:

• The 1st letter $T$ originates from position 3.
• The 2nd letter $N$ originates from position 2.
• The 3rd letter $I$ originates from position 1.
• The 4th letter $F$ originates from position 6.
• The 5th letter $E$ originates from position 4.
• The 6th letter $R$ originates from position 5.
• The 7th letter $E$ originates from position 7.
• The 8th letter $E$ originates from position 9.
• The 9th letter $R$ originates from position 8.
• The 10th letter $E$ originates from position 11.
• The 11th letter $C$ originates from position 12.
• The 12th letter $N$ originates from position 10.

This establishes the permutation sequence based on original positions: 3, 2, 1, 6, 4, 5, 7, 9, 8, 11, 12, 10.

Applying the Permutation Rule

This same permutation sequence must be applied to the word $OSCILLATIONS$.

Original word: $OSCILLATIONS$

Positions: 1 2 3 4 5 6 7 8 9 10 11 12

Letters: $O S C I L L A T I O N S$

We select letters from $OSCILLATIONS$ using the permutation sequence 3, 2, 1, 6, 4, 5, 7, 9, 8, 11, 12, 10:

• Position 3: $C$
• Position 2: $S$
• Position 1: $O$
• Position 6: $L$
• Position 4: $I$
• Position 5: $L$
• Position 7: $A$
• Position 9: $I$
• Position 8: $T$
• Position 11: $N$
• Position 12: $S$
• Position 10: $O$

Arranging these letters in the determined order results in the word $CSOLILAITNSO$. Following this logic yields the correct answer choice.

The correct answer is $CSOLILIATSNO$.
