Step 1: Observe the pattern in the code.
In the given code, the pattern involves reversing the letters in the word, swapping pairs of letters. For example:
- "VISHWANATHAN" is written as "NAAWTHHSANIV".
Similarly, "KARUNAKARANA" will follow the same pattern.
Step 2: Apply the pattern to KARUNAKARANA.
Following the pattern, we reverse and swap pairs of letters in "KARUNAKARANA", which results in "KAANRAURNAAK".
Step 3: Conclusion.
Thus, the correct answer is 1. KAANRAURNAAK.
