Understanding Copilot Capabilities in Word for the Microsoft AB-730 Exam

While preparing for the Microsoft AB-730 exam, I came across an interesting question related to the Microsoft 365 Copilot in Word that made me pause and think deeper.
The question i faced 
You are using Microsoft 365 Copilot to enhance your productivity in Microsoft Word.
Which two tasks can you achieve by using Copilot in Word?

Options:
A- Insert a table of contents based on the headings in your document.
B- Insert a custom watermark that has specific text and formatting.
C- Generate a summary of the key points in your document.
D- Customize the page margins to match your company's document standards.

I was confident that the correct answer was A&C, but I did not just want to memorize it. I wanted to clearly understand why those options were correct and why the others were not. 

How i clarified My Understanding.
During my research, i reached a platform called P2PExams. I found the same questions in their practice test material, along with a clear and logical explanation. What I really appreciated was that the explanation focused on conceptual clarity instead of just answering.

Here's the explanation i found:
Copilot in Word assists with content generation, summarization, rewriting, and structural
organization. It can analyze document headings and insert a table of contents based on
structured heading styles, supporting document navigation. It can also generate summaries of
key points, which aligns directly with generative AI text analysis capabilities.
Custom watermark formatting and precise page margin configuration are traditional Word
formatting functions and are not core generative AI capabilities of Copilot.
Therefore, the correct answers are A and C
