This question is about identifying a pattern in how letters are rearranged (coded) from one word to another. We are given an example: 'VISHWANATHAN' is coded as 'NAAWTHHSANIV'. Our task is to find the same pattern and apply it to code the word 'KARUNAKARANA'.
First, let's compare the original word and the coded word:
To figure out the rearrangement rule, we can track the position of each letter.
Let's number the positions of the letters in the original word 'VISHWANATHAN':
V1 I2 S3 H4 W5 A6 N7 A8 T9 H10 A11 N12
Now, let's see where each of these letters (identified by their original position) ends up in the coded word 'NAAWTHHSANIV':
| Original Position | Letter | New Position in Coded Word |
|---|---|---|
| 1 | V | 12 |
| 2 | I | 11 |
| 3 | S | 8 |
| 4 | H | 7 |
| 5 | W | 4 |
| 6 | A | 3 |
| 7 | N | 1 |
| 8 | A | 2 |
| 9 | T | 5 |
| 10 | H | 6 |
| 11 | A | 9 |
| 12 | N | 10 |
The table reveals the exact positional shift: The letter that was originally in position $1^{st}$ moves to the $12^{th}$ position, the $2^{nd}$ moves to the $11^{th}$, the $7^{th}$ moves to the $1^{st}$, and so on. We have established a clear mapping rule: Original Position $\rightarrow$ New Position.
Let's use this confirmed mapping rule on the word 'KARUNAKARANA'. First, number its letters:
Original Word: K1 A2 R3 U4 N5 A6 K7 A8 R9 A10 N11 A12
Now, we construct the new word by placing the letters according to the mapping rule derived from the example:
Putting these letters together in order results in the coded word: KAANRAURNAAK.
The word 'KARUNAKARANA' is written as 'KAANRAURNAAK' following the specific letter rearrangement pattern.
This matches Option 1.
