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

Solution : Given:
1. Laudanum 2. Lattice 3. Laudation 4. Latterly 5. Laudable

The first two letters are common in all the words, so we will start from the third letter of the given words.
Step 1: We can see that the third letters are u and t , and as t comes before u in the dictionary (Lattice, Latterly) will come before options (Laudanum, Laudation, Laudable).
Step 2: On comparing Lattice and Latterly, we can see Latt is common, and after that i and e are there, as e comes before ​​​i , so Latterly will come before Lattice.
Step 3: In Laudanum, Laudation, and Laudable, the first 5 letters are common, and after that n , t , and b are there, and in the dictionary b comes before n , and after that ​​​t comes.
Therefore, Laudable will be in third place, Laudanum in fourth place, and Laudation in fifth place.

So the sequence will be Latterly, Lattice, Laudable, Laudanum, Laudation, or 4, 2, 5, 1, 3. Hence, the fourth option is correct.
