Correct Answer: 2, 1, 3, 4

Solution : Given:
1. Yashmak 2. Yacht 3. Yawl 4. Yawn

Step 1: Compare the first letter of each word. Since all the words start with the same letter Y , then move on to the next letter.
Step 2: The second letter of each word is the same, i.e., a , then move on to the next letter.
Step 3: Compare the third letter of (Ya s hmak, Ya c ht, Ya w l, Ya w n). Yacht will come first as c comes before s and w in alphabetical order. Similarly, Yashmak will come before Yawl, and Yawn as s comes before w in alphabetical order.
Step 4: Compare the fourth letter of (Yaw l , Yaw n ). Yawl will come before Yawn as l comes before n in alphabetical order.

So, the sequence is Yacht, Yashmak, Yawl, Yawn, or 2, 1, 3, 4. Hence, the fourth option is correct.
