Explanation:

To determine the cost for 15 team shirts in 3 sizes and 4 colors, we need a tool to organize data (sizes, colors, shirt cost, printing cost, total cost per combination) and perform calculations efficiently. A spreadsheet (like Excel) allows creating tables, using formulas (e.g., total cost = (shirt cost + printing cost) * quantity) for multiple combinations, and easily evaluating different cost options. A calculator is good for single calculations but not for managing multiple variables and scenarios. A word processor is for text, not calculations. A database is for storing large datasets, not quick cost evaluation for this small - scale, tabular - calculation - based task.

Answer:

C. Spreadsheet
