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

Solution : Given:
1. Syringe 2. Syphilis 3. Syncretism 4. Synarchy 5. Submerge

Step 1: Compare the first letter of each word. Since all the words start with the same letter S , then move on to the next letter.
Step 2: The second letter of each word is either u or y . Based on the alphabetical order of these letters, we can arrange them – S u bmerge, S y ringe, S y philis, S y ncretism, S y narchy.
Step 3: Compare the third letter of (Sy r inge, Sy p hilis, Sy n cretism, Sy n archy). Syncretism and Synarchy will come before Syringe and Syphilis in the sequence as n comes before r and p in the alphabetical system. Similarly, Syphilis will come before Syringe as p comes before r in the alphabetical system.
Step 4: Compare the fourth letter of (Syn c retism, Syn a rchy). Syn a rchy will come before Syn c retism as a comes before c in the alphabetical system.

So, the sequence is Submerge, Synarchy, Syncretism, Syphilis, Syringe, or 5, 4, 3, 2, 1. Hence, the second option is correct.
