Which application is commonly used to view PDFs?

Correct option is B

Adobe Acrobat Reader. It is the most widely used and trusted application for viewing, printing, and annotating PDF (Portable Document Format) files. Adobe developed the PDF format, and Acrobat Reader is their free tool available across all major platforms for viewing PDF documents.

Important Key Points:

1. PDF (Portable Document Format) was developed by Adobe Systems for presenting documents independent of software or hardware.
2. Adobe Acrobat Reader is specifically designed for reading and managing PDF files.
3. While other applications can open PDFs, Acrobat Reader offers advanced PDF-specific features like annotations, filling forms, and digital signatures.

Knowledge Booster:

•       Microsoft Word can open and save PDFs, but it's primarily a word processor, not a PDF viewer.

•       VLC Media Player is used for playing audio and video files — it doesn't support PDF files.

•       Google Drive allows PDF viewing through a browser, but it is not a dedicated PDF application.

•       Advanced PDF editing and secure handling are done through Adobe Acrobat Pro, a premium version.
