Which of the following isn’t a part of a spreadsheet?a.row numberb.Column numberc.Cell addressd.Column letter

1. Break Down the Problem

We need to identify which option is not a part of a spreadsheet. The options provided are:

• a. Row number
• b. Column number
• c. Cell address
• d. Column letter

2. Relevant Concepts

In a spreadsheet:

• Row Numbers identify horizontal lines and are typically numbered.
• Column Letters represent vertical lines and are usually labeled with letters (A, B, C, etc.).
• Cell Addresses are the combination of column letters and row numbers (e.g., A1, B2).

3. Analysis and Detail

Now let's analyze the options:

1. Row Number: This is a part of a spreadsheet, as rows are numbered (1, 2, 3,...).
2. Column Number: This is not typically used; columns are labeled with letters rather than numbers.
3. Cell Address: Defined as the combination of a row number and a column letter (e.g., A1).
4. Column Letter: This is indeed used in spreadsheets to label columns.

4. Verify and Summarize

The only option that does not conventionally exist in spreadsheet terminology is Column Number since columns are represented by letters, while rows are represented by numbers.

Final Answer

b. Column number is not a part of a spreadsheet.
