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

Solution : Given:
1. Lively  2. Longer  3. Lasted  4. Lamp  5. Lost

Step 1: Compare the first letter of each word. Since all the words start with the same letter L, move to the next letter.
Step 2: The letters on the second position as per the given sequence are i , o , a , a , and o respectively. Based on the alphabetical order of these letters, now arrange the words: L a sted, L a mp, L i vely, L o st, L o nger.
Step 3: In the order of Step 2, the second letter of Lasted and Lamp is the same. So, on comparing the third letters of these two words Lamp will come before Lasted as m appears before s in the alphabetical series.
Step 4: On comparing the third letters of the remaining words Lost and Longer, Longer will be placed before Lost as n appears before s in the alphabetical series.

So, the correct sequence is Lamp, Lasted, Lively, Longer, Lost, or 4, 3, 1, 2, 5. Hence, the first option is correct.
