Answer:
=DSUM(A4:D8, "Unit Cost", A1:B2)
Explanation:
From the list of given options, it's obvious that the question relates to Excel database sum function.
The correct answer among the list of options is:
=DSUM(A4:D8, "Unit Cost", A1:B2)
Where
DSUM represents the function itself
A4:D8 represents the range
"Unit cost" represents the field
and
A1:B2 represents the criteria of the function
Analysing other options:
Option 1: The equality sign (=) before excel formulas is missing
Option 2: Sum is used instead of DSUM and there's a missing bracket before the range
Option 3: There's a missing comma between the range, the field and the criteria
Hence, the last option (4) answers the question.

Answer: Column F
Explanation: In Microsoft excel, for the sake of robustness and to aid the effectiveness of updating formulas across cells. The reference of cells are treated as relative which means that when formulas are copied across columns or within rows, they get updated automatically. However, some numbers may be treated as constants such that we do not want them to change or be updated as we move acisss cells. Thus, such numbers are treated Given absolute references, which is made possible by adding a '$' prefix before the colum alphabet or row number or both. in the scenario given above, the row has the $ prefix, hence, it is absolute and will not change but the column alphabet does not and hence, treated as relative.
