In which application would you commonly find workbooks and worksheets?

Spreadsheet software is specifically designed to manage and manipulate numerical data and support various mathematical operations. Within this type of application, workbooks serve as the main files that contain one or more worksheets. Each worksheet consists of a grid made up of rows and columns where users can input, calculate, and analyze data.

By utilizing spreadsheet software, users can harness functions and formulas effectively, making tasks such as budgeting, financial analysis, and data organization more streamlined. This environment is distinctly different from word processing software, which focuses on text documents; email clients that handle message composition and organization; and database management systems, which are oriented towards storing and retrieving structured data rather than managing numerical tables. Thus, the presence of workbooks and worksheets is a defining characteristic of spreadsheet software, making it the correct answer.
