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

Solution : Given:
1. Thresh 2. Threadbare 3. Thrice 4. Threw 5. Threat

Step 1: Compare the first, second, and third letters of each word. Since all the words start with the same letter T and are followed by h and r , so move on to the next letter.
Step 2: The fourth letter of each word is either e or i . Based on the alphabetical order of these letters, we can arrange them – Thr e sh, Thr e adbare, Thr e w, Thr e at, Thr i ce.
Step 3: Compare the fifth letter of (Thre s h, Thre a dbare, Thre w , Thre a t). (Threadbare and Threat) will come before Thresh, Threw in the sequence as a comes before s and w in the alphabetical system. Similarly, Thresh will come before Threw in the sequence as s comes before w in the alphabetical system.
Step 4: Compare the sixth letter of (Threa d bare, Threa t ). Threadbare will come before Threat in the sequence as d comes before t in the alphabetical system.

So, the sequence is Threadbare, Threat, Thresh, Threw, Thrice, or 2, 5, 1, 4, 3. Hence, the second option is correct.
