Correct Answer: Rumble

Solution : Given:
1. Russia  2. Rusted  3. Rumble  4. Royal

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: The second letter of each word is – u, u, u, o . Based on the alphabetical order of these letters, we can arrange them – R o yal, R u ssia, R u sted, R u mble
Step 3: Compare the third letter of (Ru s sia, Ru s ted, Ru m ble). Rumble will come before Russia and Rusted in the sequence as m comes before s in the alphabetical system.
Step 4: Compare the fourth letter of (Rus s ia, Rus t ed). Russia will come before Rusted in the sequence as s comes before t in the alphabetical system. Therefore, the sequence is Royal, Rumble, Russia, and Rusted.

So, the word Rumble appears second in the sequence. Hence, the third option is correct.
