Correct Answer: Pastor

Solution : Given:
1. Pectoral  2. Pastry  3. Pastor  4. Passed  5. Passport

Step 1: Compare the first letter of each word. Since all the words start with the same letter P then move to the next letter.
Step 2: The second letter of each word is either a or e. Based on the alphabetical order of these letters, we can arrange them – Pastry, Pastor, Passed, Passport, Pectoral.
Step 3:  The third letter of each word is either a or e, so the arrangement remains the same as in Step 2. Now, compare the fourth letter of (Pastry, Pastor, Passed, Passport). Passed and Passport will come before Pastry, Pastor in the sequence as s come before t in the alphabetical system. 
Step 4: Compare the fifth letter of (Passed, Passport) and the fifth letter of (Pastry, Pastor). Passed will come before Passport in the sequence as e comes before p in the alphabetical system. Similarly, Pastor will come before Pastry in the sequence as o comes before r in the alphabetical system.

So, the sequence is Passed, Passport, Pastor, Pastry, and Pectoral or 4, 5, 3, 2, 1, and in the third place Pastor is placed. Hence, the third option is correct.
