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

Solution : Given:
1. Flinching  2. Flintlock  3. Flinpites  4. Flintlocks  5. Flinchers

Step 1: Compare the first letter of each word. Since all the words start with the same letter F , move to the next letter.
Step 2: The second, third, and fourth letters of each word are the same. So, let's compare the fifth letter. The fifth letter of each word is – c, t, p . Based on the alphabetical order of these letters, we can arrange them – Flin c hing, Flin c hers, Flin p ites, Flin t lock, Flin t locks
Step 3: Compare the seventh letter of (Flinch i ng, Flinch e rs). Flinchers will come before Flinching in the sequence as e comes before i in the alphabetical system. Similarly, Flintlock(9-letter word) comes before Flintlocks(10-letter word).

The sequence is Flinchers, Flinching, Flinpites, Flintlock, Flintlocks, or 5, 1, 3, 2, 4. Hence, the third option is correct.
