Which term designates the numeric label such as B 1?

• A. B 2
• B. B 1
• C. Red cell
• D. JPP

Answer: (B)

Gridded labeling uses a letter to indicate a row and a number to indicate a column, together forming a coordinate that pinpoints a specific location. The designation written as a letter-number pair exactly serves as that coordinate, so it designates the position itself. That’s why it’s the best choice: it’s the label that identifies the exact spot. A neighboring coordinate would refer to a different position, while descriptors like “Red cell” or an acronym like “JPP” don’t function as a positional label.
