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

Solution : Given:
1. Cinnabar 2. Cinder 3. Cinema 4. Cinnamon 5. Cinchona

Step 1: Compare the first letter of each word. Since all the words start with the same letter C , move on to the next letter.
Step 2: The second and third letters of each word are the same, i.e., i and n , so move on to the next letter.
Step 3: Compare the fourth letter of (Cin n abar, Cin d er, Cin e ma, Cin n amon, Cin c hona). Cinchona will come first as c comes before n , d , and e . Cinder will come before Cinnabar, Cinema, and Cinnamon as d comes before n and e in alphabetical order. Similarly, Cinema will come before Cinnabar and Cinnamon as e comes before n in alphabetical order.
Step 4: The fifth letter of Cinn a bar and Cinn a mon is the same, i.e., a . So, move on to the next letter.
Step 5: Compare the sixth letter of (Cinna b ar, Cinna m on). Cinnabar will come before Cinnamon as b comes before m in alphabetical order.

So, the sequence is Cinchona, Cinder, Cinema, Cinnabar, Cinnamon, or 5, 2, 3, 1, 4. Hence, the fourth option is correct.
