Which E-number corresponds to Petty Officer Third Class?

• A. E-3
• B. E-4
• C. E-5
• D. E-6

Answer: (B)

In the Navy, enlisted ranks are tied to pay grades from E-1 to E-9, with each pay grade having a specific rank name. Petty Officer Third Class is the fourth pay grade, so it corresponds to E-4. The other grades map to different ranks: E-3 is Seaman, E-5 is Petty Officer Second Class, and E-6 is Petty Officer First Class.
