Correct option is C
The correct answer is (c) Deleting a row or column that contains cells referenced by a formula in another worksheet
A #REF! error typically occurs in Excel when a cell reference is invalid or broken.
The most common cause is deleting a row or column that is referenced by a formula in the worksheet. This causes Excel to lose the reference, resulting in a #REF! error.
For example, if a formula in a different worksheet refers to cell A1 on Sheet1 and A1 is deleted, the formula will show #REF! because the cell reference is no longer valid.
Information Booster:
• #REF! Error:
The #REF! error indicates that a cell reference is broken or invalid in the formula. This can happen if you delete cells or rows/columns that are referenced in the formula, or if you use an invalid or incorrect reference.
• Common Causes of #REF! Error:
Deleting rows or columns: If a cell reference in a formula is deleted (like deleting a referenced column or row).
Moving cells: When cells are moved or cut from their original position, and formulas using those cells are still trying to reference them.
Incorrectly copying formulas: Sometimes copying a formula from one cell to another can break references.
• #DIV/0! Error:
The #DIV/0! error occurs when you try to divide a number by zero or an empty cell. It will not give you a #REF! error, but rather a #DIV/0! error instead.
