A grid coordinate is defined as which of the following?

• A. Number/letter combination
• B. Letter/number combination
• C. Color code
• D. Street address

Answer: (A)

To locate a specific cell on a grid, you need two pieces of information: which row and which column. The typical approach uses a numeric label for the row and an alphabetic label for the column, and you combine them to form a grid coordinate. This number-for-the-row plus letter-for-the-column format creates a unique reference such as 7C, pinpointing one exact square on the grid. The numeric part identifies the row, the alphabetic part identifies the column, making the coordinate clear and unambiguous. Color codes describe color information and aren’t used to locate a square on a grid. A street address refers to a location within a street network, not a grid reference. In this context, the convention described is a numeric row with a letter column, so the grid coordinate is defined by a number/letter combination.
