Solution : Given:
1. Jalopy  2. Jabber  3. Jackpot  4. Jackdaw  5. Jackal

Step 1: Compare the first letter of each word, since all the words start with the same letter J , then move on to the next letter.
Step 2: The second letter of each word is a , then move to the next letter.
Step 3: Compare the third letter of each word as the third letters are b , c , and l . Based on the alphabetical order of these letters, we can arrange them – Ja b ber, Ja c kpot, Ja c kdaw, Ja c kal, Ja l opy.
Step 4: Compare the fourth letter of the words (Jack p ot, Jack d aw, Jack a l). Based on the alphabetical order of these letters, we can arrange them –  Jack a l, Jack d aw, Jack p ot.

So, the sequence is Jabber, Jackal, Jackdaw, Jackpot, Jalopy or 2, 5, 4, 3, 1. Hence, the first option is correct.
