To answer this question, you need to understand the concept of software that restricts or filters web page content.
Option A) Child-safe software - This option is incorrect because child-safe software typically refers to software that protects children from accessing inappropriate content, but it does not specifically prevent certain web pages from being displayed.
Option B) Dutch dike software - This option is incorrect because Dutch dike software refers to software that protects against flooding and has no relation to restricting web page content.
Option C) Filtering software - This option is correct because filtering software is specifically designed to prevent certain web pages from being displayed. It allows the user to set filters or restrictions based on specific criteria such as keywords, URLs, or categories.
Option D) Spam blockers - This option is incorrect because spam blockers are designed to prevent unwanted emails or messages, not to restrict web page content.
