The correct answer is D) Absolute referencing.
Absolute referencing in a spreadsheet uses dollar signs ($) before the column letter and row number (e.g., $A$1) to fix the reference to a specific cell. When the formula containing an absolute reference is copied to other cells, the reference remains unchanged, always pointing to the original cell. This is essential when a formula in an entire column needs to refer consistently to a single specific cell.
Relative referencing (e.g., A1) adjusts the cell reference based on the relative position when copied to other cells. Hybrid referencing (e.g., $A1$ or A$1$) fixes either the column or the row, but not both. A hyperlink is a link to another location or document and is unrelated to cell referencing in formulas.
