Correct Answer: Crow

Solution : Given:
1. Crumble  2. Crop  3. Croatia  4. Crow  5. Crown

Step 1: Compare the first letter of each word. Since all the words start with the same letter C , move to the next letter.
Step 2: Compare the second letter of each word. The second letter of each word is r , then move on to the next letter.
Step 3: The third letter of each word is – u, o, o, o,o . Based on the alphabetical order of these letters, we can arrange them – Cr o p, Cr o atia, Cr o w, Cr o wn, Cr u mble
Step 4: Compare the fourth letter of (Cro p , Cro a tia, Cro w , Cro w n). Crop and Croatia will come before Crow and Crown in the sequence as p and a come before w in alphabetical order.
Step 5: Cro a tia will come before Cro p as a comes before p in the alphabetical order and Cro w will come before Cro w n. So, the sequence will be Croatia, Crop, Crow, Crown, and Crumble.

Therefore, the word Crow appears third in the sequence. Hence, the first option is correct.
