Statement two and three is correct.
Statement 1 is incorrect. A relative reference changes when a formula is copied to another cell while Absolute references remain constant. However, it is safe to say that an absolute address can be preceded by a $ sign before both the row and the column values. It is designated by the addition of a dollar sign either before the column reference, the row reference, or both. Statement C is also correct. A mixed reference is a combination of relative and absolute reference and the formula (= A1 + $B$2) is an example of a mixed cell reference.

If, however, you picked data fields from two or more related tables, then when you click the “Next >” button, you will instead view a second screen which asks if you would like a “Detail” or “Summary” query. You can select the option button for the type of query that you wish to create. If you select “Summary,” then you will be able to click the “Summary Options…” button to open the “Summary Options” dialog box.
