Correct Answer: iii, iv, ii, i

Solution : Given:
(i) Treasure  (ii) Treadmill  (iii) Training  (iv) Translate

Step 1: Compare the first letter of each word. Since all the words start with the same letter T , we move on to the next letter.
Step 2: Let's move to the second letter of each word. Since all the words have the same second letter r , we move on to the next letter.
Step 3: The third letter of each word is: e, e, a, a . Based on the alphabetical order of these letters, we can arrange them: Tr a ining, Tr a nslate, Tr e asure, Tr e admill.
Step 4: Compare the fourth letter of (Tra i ning, Tra n slate). Tra i ning will come before Tran s late in the sequence as i comes before n in the alphabetical system.
Step 5: Since the fourth letter of (Tre a sure, Tre a dmill) is the same, move on to the next letter. Compare the fifth letter of (Trea s ure, Trea d mill). Trea d mill will come before Trea s ure in the sequence as d comes before s in the alphabetical system

So, the sequence is Training, Translate, Treadmill, Treasure, or (iii), (iv), (ii), (i). Hence, the fourth option is correct.
