Explanation

Transpose converts rows into columns (or columns into rows). Because the second spreadsheet has the column names stored as row data, the analyst must first transpose that data so both spreadsheets share the same column-oriented structure. Only after the orientation is aligned can a merge, concatenation, or blend be performed correctly. The other options (Blend, Merge, Concatenate) are used to combine data, not to fix structural/orientation mismatches.
