Correct Answer: 2, 4, 5, 1, 3

Solution : Given:
1. Roasted   2. Reason   3. Roger   4. Rigid   5. Ripple

Step 1: Compare the first letter of each word. Since all the words start with the same letter R , move on to the next letter.
Step 2: The second letter of each word is o , e , o , i , i . Based on the alphabetical order of these letters, we can arrange them – R e ason, R i gid, R i pple, R o asted, R o ger
Step 3: Compare the third letter of (Ri g id, Ri p ple) and (Ro a sted, Ro g er). Rigid will come before Ripple in the sequence as g comes before p in the alphabetical system. Similarly, Roasted will come before Roger as a comes before g .

The sequence is Reason, Rigid, Ripple, Roasted, Roger, or 2, 4, 5, 1, 3. Hence, the first option is correct.
