Best Answer Explained in Below-:

The correct cell reference for a range of cells that starts in cell C1 and extends to column H and down to row 10 is **B) C1:H10**. In Excel and similar spreadsheet applications, cell references are formatted using a specific syntax.

A cell reference indicates a starting cell and an ending cell within a rectangular range. The format is: **[starting column][starting row]:[ending column][ending row]**. In this case, C1 indicates the upper-left cell in the range, where column C meets row 1. The range extends horizontally to column H and vertically down to row 10, encapsulating all cells from C1 to H10.

Option A, C1:10H, incorrectly places the row number after the column letter, which is not valid in spreadsheet syntax. Option C, C1:H-10, introduces an invalid notation with a negative number, while Option D, C1:H:10, misplaces the colon. Therefore, B) C1:H10 correctly adheres to the conventional structure used for defining ranges, making it the right answer.
