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

Solution : Given:
1. Grown   2. Grape   3. Grind   4. Gesture   5. Gentle

Step 1: Compare the first letter of each word. Since all the words start with the same letter G , move to the next letter.
Step 2: Compare the second letter of (G r own, G r ape, G r ind, G e sture, G e ntle). (Gentle, Gesture) will come before (Grown, Grape, Grind).
Step 3: Compare the third letter of (Ge s ture, Ge n tle) and (Gr o wn, Gr a pe, Gr i nd). Gentle will come before Gesture in the sequence as n comes before s in the alphabetical system. Similarly, the order for the second set is Grape, Grind, Grown.

So, the sequence is Gentle, Gesture, Grape, Grind, Grown, or 5, 4, 2, 3, 1. Hence, the third option is correct.
