Correct Answer: 1, 3, 4, 2

Solution : Given:
1. Assassination 2. Association 3. Assimilate 4. Assimuthual

Step 1: Compare the first, second, and third letters of each word. Since all the words have the same letter A , s , and s , so move on to the next letter.
Step 2: The fourth letter of each word is a , i , or o . Based on the alphabetical order of these letters, we can arrange them – Ass a ssination, Ass i milate, Ass i muthual, Ass o ciation.
Step 3: Compare the sixth letter of (Assim i late, Assim u thual). Assimilate will come before Assimuthual in the sequence as i comes before u in the alphabetical system.

So, the sequence is Assassination, Assimilate, Assimuthual, Association, or 1, 3, 4, 2. Hence, the third option is correct.
