Explanation:

- Let's analyze how MACHINE is written as CAMHENI.

- The first two letters "MA" are reversed to become "CA".

- The last four letters "HINE" are reversed to become "ENIH".

- The sequence is altered, combining "CA" and "ENIH" with an alteration in position.

- Now, apply the same logic to MONSTER.

- Reverse the first two letters "MO" to "OM".

- Reverse the last four letters "STER" to "RETS".

- Organize as per the identified pattern.

- Review the options:

1. OMNSETR - Follows pattern.

2. NOMSRET - Not aligning with pattern.

3. SNOMRET - Not aligning with pattern.

4. NOMETSR - Not aligning with pattern.

- The transformed form of MONSTER following the pattern is "OMNSETR".

- Option 1: OMNSETR
