Based on the task and the question provided, let's analyze the options for internet safety according to the text: 1. **Avoid using the internet completely** - This option is often unrealistic and impractical, as the internet is necessary for many aspects of modern life. 2. **Use strong passwords and not share personal information online** - This is a widely recommended practice for internet safety. Strong passwords help protect against unauthorized access, and not sharing personal information helps protect privacy. 3. **Share passwords only with friends** - This is generally not advised. Even with trusted friends, sharing passwords increases the risk of unauthorized access. 4. **Rely on social media for privacy** - Social media platforms may not always prioritize users' privacy, and using them solely for privacy can be risky. For internet safety, the most logical and commonly advised choice is **B) Use strong passwords and not share personal information online**. This aligns with best practices for maintaining personal security and privacy on the internet.
