Final Answer:
Avoiding pasting data as embedded objects, as it may significantly increase the file size, is NOT a key principle of pasting Excel data and financial models into PowerPoint. Option D.
Step-by-step explanation:
Effective integration of Excel data into PowerPoint is crucial for financial presentations. One key principle is to keep the data in Excel as long as possible for easy updates (Option B). This ensures that the financial models remain dynamic and any changes can be efficiently reflected in the presentation.
Another important principle is to use Paste Special to paste values or pictures, providing better control over formatting (Option C). This allows for a cleaner transfer of data, minimizing formatting issues and maintaining the professional look of the financial models in the presentation.
However, contrary to common practice, it's not necessary to always format the data in PowerPoint for more flexible formatting options (Option A). This might introduce unnecessary complexities and hinder the seamless integration of financial information.
In summary, the correct answer is D. Avoid pasting data as embedded objects to prevent a significant increase in file size. This ensures the efficient and practical integration of Excel data into PowerPoint presentations, maintaining both accuracy and manageability.
