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

Solution : Given:
1. Range   2. Radar   3. Race   4. Rack   5. Rant

Step 1: Compare the first letter of each word. Since all the words start with the same letter R , move to the next letter.
Step 2: Compare the second letter of each word. The second letter of each word is a , then move on to the next letter.
Step 3: The third letter of each word is – n, d, c, c, n . Based on the alphabetical order of these letters, we can arrange them – Ra c e, Ra c k, Ra d ar, Ra n ge, Ra n t
Step 4: Compare the fourth letter of (Rac e , Rac k ). Race will come before Rack in the sequence as e comes before k in the alphabetical order.
Step 5: Compare the fourth letter of (Ran g e, Ran t ). Range will come before Rant in the sequence as g comes before t in the alphabetical order.

So, the sequence will be Race, Rack, Radar, Range, Rant, or 3, 4, 2, 1, 5. Hence, the first option is correct.
