Answer: (B)

The correct choice highlights that a .doc file is specifically a Microsoft Word document, while a .pdf file is known as a Portable Document Format file. This distinction is important because it reflects the fundamental purposes and functionalities of the two file types.

A .doc file, created by Microsoft Word, is designed for word processing and allows for extensive editing, formatting, and collaboration. Users can change text, fonts, styles, add images, and perform various editing tasks. On the other hand, a .pdf file is intended for viewing and sharing documents in a format that preserves the layout and appearance across different devices and platforms. The design of a .pdf means it typically does not allow for easy editing like a .doc file does, ensuring the layout remains consistent for all viewers.

This understanding is vital for selecting the appropriate file format based on the task at hand—whether you need to create or modify text (using .doc) or share a document in a fixed format (using .pdf).
