Correct Answer: 2, 1, 4, 3

Solution : Given:
1. Stilt 2. Stifle 3. Stink 4. Stingy

Step 1: Compare the first, second, and third letter of each word. Since all the words have the same letters S , t , or i , so, move on to the next letter.
Step 2: The fourth letter of each word is f , l , or n . Based on the alphabetical order of these letters, we can arrange them – Sti f le, Sti l t, Sti n k, Sti n gy.
Step 3: Compare the fifth letter of (Stin k , Stin g y). Stingy will come before Stink in the sequence as g comes before k in the alphabetical system.

So, the sequence is Stifle, Stilt, Stingy, Stink, or 2, 1, 4, 3. Hence, the third option is correct.
