Internet forums are commonly referred to as discussion forums.
Reasoning:
Internet forums are online platforms where people can engage in discussions and share information on various topics. They provide a space for users to post messages, ask questions, and participate in conversations with other members of the forum community. These forums are commonly referred to as discussion forums because their primary purpose is to facilitate discussion and exchange of ideas.
Explanation:
- Chat forums: While internet forums do involve chatting and communication between users, the term "chat forums" is not commonly used to refer to them. The term "chat" typically refers to real-time conversations, while forums are more suited for asynchronous discussions.
- Mail forums: Internet forums do not typically operate through email, so the term "mail forums" is not an accurate description.
- Blogging forums: Blogging forums specifically focus on discussions related to blogging and may not cover a wide range of topics. Internet forums, on the other hand, cover a wide range of subjects and are not limited to blogging.
Therefore, the correct answer is B: Discussion forums.
