Correct Answer: 2, 5, 1, 4, 3, 6

Solution : Given:
1. Banished 2. Bandage 3. Bannister 4. Bankrupt 5. Bandwagon 6. Banquet

Step 1 : Compare the first letter of each word. Since all the words start with the same letter B , we move on to the next letter.
Step 2 : Compare the second letter of each word. Since all the words have the same second and third letters a and n , let's move on to the next letter.
Step 3 : The fourth letter of each word is: i, d, n, k, d, q . Based on the alphabetical order of these letters, we can arrange them – Ban d age, Ban d wagon, Ban i shed, Ban k rupt, Ban n ister, Ban q uet.
Step 4 : Compare the fifth letter of (Band a ge, Band w agon). Bandage will come before Bandwagon in the sequence as a comes before w in the alphabetical system.

So, the sequence is Bandage, Bandwagon, Banished, Bankrupt, Bannister, Banquet or 2, 5, 1, 4, 3, 6. Hence, the third option is correct.
