The correct answer is Relative.

Key Points

• Relative cell references are the default type of cell reference in MS Excel. When a formula containing relative references is copied to another cell, the references adjust based on the relative position of rows and columns.
• For example, if you have a formula in cell A1 referencing B1, and you copy the formula to cell A2, the reference will adjust to B2. This is because relative references automatically change based on the location where they are moved.
• Relative references are useful for repetitive calculations across multiple rows or columns. Hence, the correct option is Relative.
• Active cell reference is not the default reference type. An active cell is simply the currently selected cell in Excel, and the term does not describe the type of reference used in formulas.
• Absolute references are defined with a "$" sign (e.g., $A$1), which ensures that the reference does not change when the formula is copied to another cell. This is not the default type of reference. Hence, option Absolute is incorrect.
• Mixed references combine relative and absolute references. For example, $A1 or A$1. These references lock either the row or column but are not the default reference type. Hence, option Mixed is incorrect.
• Hence, the correct answer is Relative.

Additional Information

• Cell references in Excel:
• Relative references: Adjust automatically when copied or moved to another cell.
• Absolute references: Do not change when copied or moved, denoted by "$" signs (e.g., $A$1).
• Mixed references: Partially locked references, e.g., $A1 (column locked) or A$1 (row locked).
• Practical applications:
• Relative references are particularly helpful in creating formulas that need to be reused across rows or columns, such as in summing multiple rows or calculating percentages.
• Absolute references: Useful for fixed values, like tax rates or constants, which should not change regardless of where formulas are copied.
• Mixed references: Useful for scenarios where you need to lock either the row or column while allowing the other to adjust dynamically.
• Examples:
• Relative reference example: =A1+B1, when copied to another row, becomes =A2+B2.
• Absolute reference example: =$A$1+B1, when copied, still refers to $A$1.
• Mixed reference example: =$A1+B$1, where either the row or column remains locked.

Important Points

• Key differences between reference types:
• Relative references are dynamic and adjust automatically.
• Absolute references are fixed and do not change.
• Mixed references allow partial locking of either row or column.
• Usage scenarios:
• Relative references are ideal for repetitive calculations.
• Absolute references are used for constants, such as fixed rates.
• Mixed references are useful for complex formulas requiring partial adjustments.
