Final Answer:
To make Header 1 look like Header 2 in Excel, you would use the tool "Conditional Formatting" (Option B).
Step-by-step explanation:
In Excel, "Conditional Formatting" is the tool you'd employ to dynamically format cells based on specific conditions. This enables you to make Header 1 look like Header 2 by applying formatting rules. For instance, if you want cells in Header 1 to change color or font style based on their values or relations to Header 2, Conditional Formatting allows for this dynamic adjustment.
On the other hand, "Text formatting" primarily deals with the appearance of the text itself, "Pivot Tables" is used for data analysis and summarization, and "Chart Tools" is for creating and modifying charts in Excel. These tools are not specifically designed for making one header look like another.
Option B is the answer.
