To answer this question, we need to understand the characteristics and differences between blogs and wikis.
Option A) Blogs have comments while Wikis do not - This option is incorrect. Both blogs and wikis can have comments. Comments allow readers to provide feedback or engage in discussions about the content of the blog post or wiki page.
Option B) Blog is an advanced form of a wiki - This option is incorrect. Blogs and wikis serve different purposes and have different structures. A blog is typically a platform for an individual or a small group to publish and share their ideas, opinions, or experiences. It is usually presented in a chronological format, with the most recent posts appearing at the top. On the other hand, a wiki is a collaborative platform that allows multiple users to create, edit, and organize content. It is not an advanced form of a blog but rather a different type of platform.
Option C) Blog is usually centered around one person, while wiki is many-to-many - This option is correct. Blogs are typically centered around one person or a small group of authors who share their individual perspectives or experiences. The content on a blog is usually presented in a personal or subjective manner. In contrast, wikis are designed for collaboration and knowledge sharing among multiple users. They allow many-to-many interactions, where users can create, edit, and contribute to the content collectively.
Option D) Wiki is usually centered around one person, while Blog is many-to-many - This option is incorrect. The statement is the opposite of the correct answer. As mentioned earlier, blogs are usually centered around one person or a small group, while wikis are designed for many-to-many interactions.
Therefore, the correct answer is option C) Blog is usually centered around one person, while wiki is many to many. This option accurately represents the typical characteristics and purposes of blogs and wikis.
