Which code letter maps to Queen?

• A. P
• B. Q
• C. O
• D. K

Answer: (B)

Understanding how code letters map to the words they stand for is the main idea. This system uses the initial letter of the term as the code letter, so Queen is represented by the letter that begins with Q. Therefore, the code letter for Queen is Q. The other options don’t fit because they start with different letters, pointing to different terms (P for a term starting with P, K for something starting with K, O for something starting with O).
