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
