Understanding Cell Ranges in MS Excel

In Microsoft Excel, a cell range refers to a block of cells. This block can be a single cell, a row segment, a column segment, or a rectangular block covering multiple rows and columns.

To reference a contiguous range of cells, you typically specify the starting cell's address followed by a colon (:) and then the ending cell's address. The starting cell is usually the top-left corner of the range, and the ending cell is the bottom-right corner.

Identifying the Correct Cell Range Reference

The question asks for the cell reference for a range that starts at cell B1 and extends to column G and down to row 10. This means the range covers all cells from column B to column G and from row 1 to row 10.

The top-left cell of this range is B1.

The bottom-right cell of this range is where column G and row 10 intersect, which is cell G10.

Therefore, the correct way to represent this contiguous range in MS Excel is by using the start cell, a colon, and the end cell: B1:G10.

Analyzing the Given Options

• Option 1: G1 - G10

  This format uses a hyphen and suggests a range within a single column (G). While hyphens are sometimes used in other contexts, they are not the standard separator for a contiguous range in Excel cell references. This option is incorrect as the range starts in column B.

• Option 2: B1. G10

  This format uses a dot (.). A dot is not used in standard Excel cell range notation. This option is incorrect.

• Option 3: B1, G1

  This format uses a comma (,). A comma is used in Excel to separate multiple individual cells or non-contiguous ranges (e.g., B1, G10 refers to two specific cells, not the range between them; B1:B5, D1:D5 refers to two separate ranges). This option is incorrect for a single contiguous block.

• Option 4: B1: G10

  This format uses a colon (:) between the starting cell (B1) and the ending cell (G10). This is the standard and correct way to represent a contiguous range of cells from B1 to G10 in MS Excel. This option correctly identifies the top-left cell (B1) and the bottom-right cell (G10) of the specified range and uses the correct separator (:).

Based on the standard rules for referencing cell ranges in MS Excel, the format B1:G10 accurately represents the specified range.
