Correct Answer: 1, 2, 4, 3

Solution : Given:
1. Claim 2. Clearly 3. Clerk 4. Clerical

Step 1: Compare the first and second letters of each word. Since all the words start with the same letter C , followed by l then move on to the next letter.
Step 2: The third letter of each word is either a or e . Based on the alphabetical order of these letters, we can arrange them – Cl a im, Cl e arly, Cl e rk, Cl e rical.
Step 3: Compare the fourth letter of (Cle a rly, Cle r k, Cle r ical). Clearly will come before Clerk, Clerical in the sequence as a comes before r in the alphabetical system.
Step 4: Compare the fifth letter of (Cler k , Cler i cal). Clerical will come before Clerk in the sequence as i comes before k in the alphabetical system.

So, the sequence is Claim, Clearly, Clerical, Clerk or 1, 2, 4, 3. Hence, the fourth option is correct.
