Correct Answer: 3, 4, 1, 2

Solution : Given:
1. Pearl 2. Peasant 3. Pea 4. Peanut

Step 1: Since all the words start with the same letter P , so move on to the next letter.
Step 2: The second and third letters of each word are the same, i.e., e , and a . So, move on to the next letter.
Step 3: Now, as the word Pea has no more letters, Pea will come before Pearl, Peasant, and Peanut.
Step 4: Compare the fourth letter of (Pea r l, Pea s ant, Pea n ut). Peanut will come before Pearl, and Peasant as n comes before r and s according to the alphabetical system. Similarly, Pearl will come before Peasant as r comes before s according to the alphabetical system.

So, the sequence is Pea, Peanut, Pearl, Peasant, or 3, 4, 1, 2. Hence, the second option is correct.
