If given code 60S, which surname is it?

Answer: D — Henry

Decoding codes that map to surnames uses a fixed reference or key. The code you’re given, 60S, is interpreted according to that key, and in the set used for this question it designates the surname Henry. That’s why this one stands out as the correct match—the other surnames don’t align with the 60S entry in the same coding system, so they don’t fit when decoded with the same key. When you study these, focus on learning the specific SAMPLEcode-to-surname mapping used in your course material, then apply it consistently to decode each item rather than guessing.
