Correct Answer: ii, i, iii, iv

Solution : Given:
i. Worrisome ii. Wonderful iii. Worthless iv. Wrong

Step 1: Consider the first letter of each word. Since all the words start with the same letter W , move on to the next letter.
Step 2: The second letter of each word is either o or r . Based on the alphabetical order, we can arrange them as – W o rrisome, W o nderful, W o rthless, and W r ong.
Step 3: Consider the third letter of (Wo r risome, Wo n derful, Wo r thless). Wo n derful will come before (Wo r risome, Wo r thless) as n comes before r in the alphabet.
Step 4: Consider the fourth letter of (Wor r isome, Wor t hless). Wor r isome will come before Wor t hless as r comes before t in the alphabet.

So, the sequence is Wonderful, Worrisome, Worthless, Wrong or, ii, i, iii, iv. Hence, the second option is correct.
