Correct Answer: 4, 3, 2, 1

Solution : Given:
1. Forest 2. Fascinating 3. Fantastic 4. Fabulous

Step 1: Since all the words start with the same letter F , so move on to the next letter.
Step 2: The second letter of each word is either o or a . The arrangement can be – (Fascinating, Fantastic, Fabulous), Forest.
Step 3: Compare the third letter of (Fa s cinating, Fa n tastic, Fa b ulous). Fabulous will come before Fascinating, and Fantastic as b comes before s , and n according to the alphabetical system. Similarly, Fantastic will come before Fascinating as n comes before s according to the alphabetical system.

So, the sequence is Fabulous, Fantastic, Fascinating, Forest, or 4, 3, 2, 1. Hence, the third option is correct.
