Answer: Option C
A worksheet is a computerized spreadsheet that is used to store and organize data in rows and columns. The three types of data that can be entered in a worksheet are:

• Numbers/Characters: Numeric values or textual data can be entered into the cells of a worksheet. These can be used for calculations or as labels for the data.
• Text: This is any textual data that is entered into a cell. Text is typically used to provide a label or description for the data.
• Logic: Logical values are used to represent true or false conditions in a worksheet. Logical values are often generated by formulas or functions.

Formulas and functions are not themselves types of data that can be entered into a worksheet. Rather, they are tools that are used to manipulate data that has already been entered into the worksheet. Formulas are mathematical expressions that can be used to perform calculations on the data in a worksheet. Functions are pre-defined formulas that are designed to perform specific tasks, such as finding the sum of a range of values or counting the number of cells that meet certain criteria.
Logic is a type of data that is used to represent true or false conditions in a worksheet. In Excel, logical values are represented by the keywords "TRUE" and "FALSE", and can be generated by a variety of functions and formulas. Logical values are often used in conditional formatting, where cells are formatted based on the value of the logical expression.
In conclusion, the correct answer to the question is Option C: logic. Formulas and functions are not types of data that can be entered into a worksheet, but are rather tools used to manipulate data, whereas logic is a type of data that is used to represent true or false conditions in a worksheet.
