B7:B9 indicates: A. Cells B7 and cell B9 only B. Cells B7 through B9 C. Cell B8 only D. None of the above

The correct answer is: B. Cells B7 through B9

A range in Excel is a group of cells that are identified by their cell addresses. The cell addresses are separated by a colon (:). For example, B7:B9 indicates cells B7, B8, and B9.

Option A is incorrect because it only includes cells B7 and B9. Option C is incorrect because it only includes cell B8. Option D is incorrect because it is not a valid range.
